Guest jj mac Posted September 10, 2008 Posted September 10, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Franc I have ascertained that my motherboard is based on the Intel i430 FX Triton Chipset and was manufactured by Fugutech. Identification marks/Part numbers on the RAM Chips removed from the Computer are as follows: TI - 70 TMS44409DJ OE 5A AIE81 Note: I had difficulty distinguishing between the letter I and number 1 and between the letter O and the number 0 in the above. Please make any correction if necessary. There are 8 chips ( in 2 groups of 4) on each of the two modules removed. The Modules are made by Texas Instruments with part no. TM124FBK32S - 70 96141 Not having an internet connection on the WIN 98SE computer I downloaded & saved the Celem Cache Test program & on another Computer. I unzipped the files and copied them to floppy disk. The unzipped program contained 5 files including 2 No. executable files, CCT386.EXE AND CCT4GW.EXE. I used the Windows startup disk to boot the Computer to an A:\ prompt. I then inserted the floppy containing the Celem test program in drive A, I didn’t know which of the two applications I should run. When I tried to run CCT386.exe I got an error message “A:\CCT*.FON not found”. I then tried to run CCT4GW.exe and got a fatal error “Syntax - DOS4G (executable. xxx)”. I don’t know where I have gone wrong. Franc you gave me a web link to a program for testing the RAM which I did not follow up because I had decided that I would be changing the RAM which I still intend to do. However, at Glee’s suggestion I have run Windows Memory Diagnostic Extended Test Suite for 15 hours and no errors were found. Glad to hear that I should be able to run SEATOOLS on my WIN 98 Computer with 40MB of RAN notwithstanding the stated min. requirements. I will try it out in a day or two and let you know how I get on. Many thanks for all your help not forgetting the clarification of the opus operandi for testing the COM Port. -- JJ MacA "Franc Zabkar" wrote: > On Mon, 8 Sep 2008 15:11:01 -0700, jj mac <jj > mac@discussions.microsoft.com> put finger to keyboard and composed: > > >Thank you Franc > >The COM port is enabled in the BIOS setup.

The autoexec.bat file created a 3MB RAM disc into which was extracted the SeaTools executable ... with about 2MB to spare. Anyway, I went through the procedure to download the latest version (V2.07) and got to this page: http://www.seagate.com/www/en-us/support/downloads/seatools/seatooldreg The requirements were listed as: ==================================================================== You can run SeaTools for DOS to test your disc drive if your PC has: at least one (1) disc drive. Seagate Technology disc drives will support enhanced features. an IBM / Intel compatible PC with a 386 or greater processor. SVGA 800 x 600 or greater graphics capability. at least 8 megabytes of RAM. 1.44 megabyte floppy disk or CD-ROM drive for the bootable SeaTools application. ==================================================================== However, the new readme file once again asks for a Pentium with 64MB of RAM, but only a 640x480 VGA resolution. <shrug> V2.07 still runs fine on the 486 box, though, and it still creates a 3MB RAM disc. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
Guest jj mac Posted September 11, 2008 Posted September 11, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Franc Many thanks for the information. Regarding the Celem Cache Test program I downloaded the zip file to memory stick where i unziped it. The unziped files got mixed with others on the memory. I identified 5 files which I copied to a floppy disk but there were clearly others which I missed. I will check that out shortly. I Have checked the com port on the Computer. (Pin nos.1 to 5 L to R top row 6 to 9 L to R bottom row) Results: Pins 2 to 3 No Flash when shorted. DC voltage between pins 12 V Pins 4 to 6 No Flash when shorted. DC voltage between pins 9V Pins 7 to 8 No Flash when shorted. DC voltage between pins 9V Can any conclusions be drawn from these results.?

Guest jj mac Posted September 12, 2008 Posted September 12, 2008 Re: Mouse not detected and Windows 98SE Freeze issues I have now run the Celem Cache Test. The results show that the CCT rises from 3700 to a peak of 3710 at about 4.2KB, drops to 800 at about 11KB,and continues at about 800 to about 260KB, then drops to about 530 at 406kb and continues at about that level to 2580kb and beyond. The peaks are at 2.8kb(3500) , 11kb – 260kb (800) & 400kb – 2580kb and beyond (530) I am not sure how to interpret the CCT axis. Do these results mean that L1 cache (CPU) is 2.8KB, L2 Cache (Motherboard) is 260KB & System RAM is 2580+ KB (the graph continues beyond 2580kb) ? These results are more precisely shown in the following table: They differ a little from the figures I read from the graph.

L1 cache appears to be about 8KB, L2 cache = 256KB. The specs for a P120 suggest that this CPU should have an 8K data cache and 8K code cache, so I guess your results are OK. System RAM is 2580+ KB, as you say. The test works by "growing" a program until it fits into the amount of memory being tested. For example, if a program can fit completely into L1 cache, then it will run at L1 cache speeds. If it overflows L1 cache, then its execution speed will start to degrade until, at double the cache size, the program loses all benefits associated with the L1 cache and now runs at the speed of L2 cache. Similarly, when it grows to be twice the size of L2 cache, then it runs at the speed of main memory. This means you should see a plateau until around 256KB (+L1 cache), then a gradual drop to the next plateau at 512KB (+L1 cache). >The question is can I install more than 64MB of RAM on a motherboard based >on Intel Triton i430 FX chipset with Pipeline Burst Cache. The results are showing that L2 cache is currently enabled and working. The Celem Cache Test won't tell you if L2 cache will be completely disabled after you increase the RAM beyond 64MB. You will need to run the test again afterwards to confirm or disprove this. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
Guest jj mac Posted September 14, 2008 Posted September 14, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Thanks MEB for that useful information in view of which I have decided to replace the existing 4 modules (total 40MB) with 2 modules each of 32 MB (total 64MB). I would ,however, like to use 100nsec SDRAM as a replacement for the existing EDO 70nsec DRAM which is now difficult to come by and more expensive than SDRAM. Would it be permissible to make that substitution? You enquired if I had yet found the manufacturer of the motherboard. I could not find any reference numbers or the maker’s name on the motherboard. I scanned the computer with "ctbios" which recorded that the bios make was AWARD Modular Bios v4.50G, Award id string 01/05/96-i430FX-2A59CF54C-00 AND the Chipset is i430FX //Intel Triton-FX. There was some other information which I could not make out as it is in German.

The test uses an output pin to drive an input pin, thereby testing both pins. It appears that your mouse or COM port are failing intermittently. I'd switch your mouse to the other COM port.

Guest jj mac Posted September 14, 2008 Posted September 14, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Thanks for interpreting the results of the Celem Cash Test. The tabulated results appear to have got scrambled in transmission but you were able to gleam enough info. therefrom. As stated in my reply to MEB I have decided not to exceed 64 MB of RAM but I would like to substitute 100nsec SDRAM for the existing 70nsec DRAM, if that is permissible. However, since Windows Diagnostics, after running for 15 hours, gave the RAM a clean bill of health I may put off doing so unless/until I can find what is causing the lockups. Since reinstalling Windows I have not added any additional programs so it could hardly be caused by the Computer running out of memory. I have run SeaTools for Dos v1.10 PH . Both the short legacy test and the long “Read Scan Test” (which I ran twice) passed. So the HDD appears to be OK. I am not too concerned about a possible fault in the COM1 port so long as I can use a wireless mouse. Provided of course that any such fault is not part of the more serious lockup problem. Did “Com Test” results show any fault in COM1 Port.? My post of 9/11/2008 at 2.35PM PST refers.

Guest jj mac Posted September 16, 2008 Posted September 16, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Franc I am pleased to have your confirmation that the ComTest passed and to be able to report that my serial mouse has started to work again. Before carrying out the ComTest I had removed the COM1 port from the Computer unplugging the connector from the motherboard. I did so to check that there was no obvious defect in the ribbon cable and the pins in the port socket. Having replaced the port I carried out the COMTESTS. I then connected the serial mouse without disconnecting the wireless mouse which I had been using. I was surprised not to get a message to tell me that Windows did not detect a mouse. The mouse pointer appeared on screen but the mouse, however, could not move or control it. I concluded that the fault was still there but after receiving your confirmation that the COM 1 port was OK I reconnected the serial mouse but this time I disconnected the wireless mouse. I was pleasantly surprised to find the serial mouse worked. Furthermore the Computer lockups have also greatly reduced. It would appear that the connection of the ribbon cable to the motherboard had developed a fault which was corrected by the simple action of removing and replacing the ribbon plug. It is now obvious that the wireless Mouse connected to the USB2 port is the main culprit causing Lockouts. The USB2 5Port Adapter Card which I installed a few months ago might also be implicated. I hope, however, to be able to retain the USB ports. Would moving the card to a different slot or increasing the RAM help? I can confirm that my motherboard is a Fugutech M506 board with 4no.72 pin Simm slots at present containing 2 no. 4M modules of EDO Dram & 2 no. 16M ditto. If I had done my homework properly I should have known that SDRAM was not supported on this board. I am now thinking of replacing the two 4M modules with two 32M modules (total 64M). In the first instance I will leave the existing two 16M modules (total 32M) I will remove them if there is a problem. If they can remain I will have a total of 96M DRAM, a big improvement on 40M. With the mouse now working and the lockouts occurring less frequently the problems with this computer are now largely resolved. Be assured that your patience and help with the running of test programs and explaining the results is very much appreciated.

Guest MEB Posted September 16, 2008 Posted September 16, 2008 Re: Mouse not detected and Windows 98SE Freeze issues Okay, so you're both jj mac and this entity apparently. I see you have confirmed the Comm port issue to Franc, AND you realized the SDRAM [which some have misconstrued in various articles and web pages and which you apparently though was the same pin configuration] will not work with your system {your's supports 72 pin FPM/EDO}, as you have now confirmed the model for the board. Your intended memory installation [in your other post] should now work. It is always best to use ALL EDO or FPM memory, mixing can cause issues. You also note that the issues likely occurred AFTER installation of the USB adapter. You have also noted that two mouse [wireless and serial] installed will not work. That is not an uncommon error/issue. The mouse holds a special place and reliance in Windows/GUI systems... It may be: you have corrupted the system with the installation/drivers for the USB device. Remove ALL drivers and references to the device and USB, and either re-install the driver OR try the Maximus Decim Universal driver AFTER the complete removal of the other [Hub and subs]. Make sure to re-start after each phase [removal and installation]. AFTER either re-installing the old/original driver or PREFERABLY the Maximus Decim, try pointing the install process to the install folder for the wireless mouse so it can find the INF for *only* the wireless {it is likely needed} while retaining the Universal driver. Remember you may need to also remove the old serial mouse entry, if necessary via Safe Mode [ghost entry, check for other issues while reviewing Device Manager and Add/Remove in both Normal and Safe Modes]. -- MEB a Peoples' counsel _ _ ~~ "stalin12" <stalin12.315ada1@news.win98banter.com> wrote in message news:stalin12.315ada1@news.win98banter.com... | | I am not too concerned about a possible fault in the COM1 port so long | as I | can use a wireless mouse.

If your motherboard is the same as the one in the photos I posted, then it uses a UMC UM8663 Super-IO chip which incorporates a floppy drive controller, two IDE hard drive ports, two COM ports, and a parallel printer port. I believe the nearby UM8667 (?) chip has the RS232 drivers for the two COM ports. If the mouse works on COM2 but not on COM1, then I would suspect the UM8667 chip or the internal cable between the motherboard header and the DB9 connector on the slot bracket. If the mouse fails on both ports, then I would suspect the mouse itself, or the UM8663 chip. However, if the Super-IO chip is faulty on both COM ports, then I would also expect faults in the chip's other functions, ie floppy, parallel printer, hard drive. Since this does not appear to be the case, then the UM8663 is unlikely to be faulty. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.
