Guest Nuno Gomes Posted September 25, 2008 Posted September 25, 2008 Hello, I have applications developed in CLIPPER and they were developed in DOS. In Windows98 there were commands to charge the OS in high memory to run DOS programs. Commands like: DEVICE=C:\DOS\HIMEM.SYS /TESTMEM:OFF DEVICE=C:\DOS\EMM386.EXE AUTO RAM DOS=HIGH DEVICEHIGH /L:1,15872 =C:\DOS\DISPLAY.SYS CON=(EGA,,1) But in Windows XP how that works?... Now, i'm having problems running such applications... Any ideias will be appreciated. Thanks, Nuno Gomes

Please quote specific error messages! One way to get around such issues is to run the application on a "Virtual PC" - see here: http://www.microsoft.com/windows/virtualpc/default.mspx. However, depending on the nature of your problem, there might be simpler solutions.
Guest Nuno Gomes Posted September 25, 2008 Posted September 25, 2008 Re: Run DOS Based programs I have aplications developed in CLIPPER with databases in DBASE. It appear the message: "Cannot create VM swap file" and the application stops. Thank you for your help.

Multiposting vs Crossposting http://www.blakjak.demon.co.uk/mul_crss.htm Questions regarding XP should be posted to appropriate Windows XP groups.

Guest Nuno Gomes Posted September 25, 2008 Posted September 25, 2008 Re: Run DOS Based programs I have find the solution: Edit config.nt and autoexec.nt. This files have the configuration to run DOS programs. But let me ask one more thing: The DOS only read/write in a disk with a max capacity of 2Mb. Using the Windows XP to run DOS programs in a disk with 40Gb what happens? When the data in the disk go over 2 Mb the CLIPPER program works without problem?... Thank you for your help.

Guest Nuno Gomes Posted September 25, 2008 Posted September 25, 2008 Re: Run DOS Based programs The problem is that i can't find a group to post questions about Windows XP... What is the correct group?.. Thank you, Nuno Gomes
Guest Bob I Posted September 25, 2008 Posted September 25, 2008 Re: Run DOS Based programs 2 MB is ONLY if the DOS is working with a FAT12 file system. But then XP isn't DOS, or using DOS or using a FAT12 filing system. Nuno Gomes wrote: > I have find the solution: > Edit config.nt and autoexec.nt.

Now that I know that there are other threads on the same subject I'm reluctant to contribute any further since other people might have given you appropriate answers in the other newsgroups.
