I have been restoring a small size PC HP Pavilion 4403 and it is limited to two PCI and two ISA buses because of form factor and I was using the onboard VGA video but in some games there were lines going up and down so I use a PCI S3 trio64 video card and this fixed it but now if I use a game that needs some ems ram like in the line for config.sys "DEVICE=C:\DOS\EMM386.EXE 4096 RAM I=BOOO-B7FF" the 4096 RAM part disables accessing my D: drive in dos it says no such drive or specification but if I use "Noems" I can access it. Im using an 80 wire cable for my DVD drive setup as a master on the secondary IDE, and for dos 6.2:

Config.sys
DEVICEHIGH=C:\CDROM\OAKCDROM.SYS /D:mscd001

Autoexec.bat
LH C:\CDROM\MSCDEX.EXE /D:mscd001 /L:D

Is there some kind of error when it tries to load oakcdrom.sys driver?

The line should be
DEVICE=C:\DOS\EMM386.EXE RAM I=B000-B7FF

You don't need the "4096" and make sure you actually spell B000-B7FF correctly (with zeros and not capital O's the way it looks in your message).

Right I found something out, all my problems go away if I remove the "I=B000-B7FF" from the EMM386.EXE config.sys line ie keep it at "DEVICE=C:\DOS\EMM386.EXE RAM" I have spelt it correctly with number zeros and not the letter O so why would this parameter at this line of code cause so many problems. Hay dr.st why do I need to remove 4096 from the RAM setting I thought this controlled how much EMS is created. Mrau from your post im useing 160Mb of SDRAM one stick is 32Mb and the other is 128Mb, and Baoran there are no errors on boot up for oakcdrom.sys or any other device. Im also now trying to figure out why a game has bad audio but I think its a game related problem as some other games run just fine.
