I've been fiddling around with my 486 today, and I found out that I could save 15 Kb of conventional memory by replacing the CD-driver nec_ide.sys with sbide.sys in config.sys. Nec_ide.sys uses 25 Kb, but sbide.sys uses only 10 Kb. I had used nec_ide.sys since I have a NEC CD-unit, but Creative's sbide.sys seems to work just as well so I see no reason not to use that one from now on.
What other CD drivers are out there and is there any difference between them apart from their memory consumption, i.e. Is there a reason not to choose the most memory efficient one as long as it works?
I also have a problem of loading both nec_ide.sys and sbide.sys into the upper memory with DEVICEHIGH. Sbide.sys uses 9984 bytes of conventional memory, but my largest free upper memory block is 13488 bytes, so I see no reason to why it wouldn't fit in there.
