I teach a few classes where we use old 386's for test runs for dissassembly etc. One opf the problems we have had is the CD's we get the students to fit test bench style work on one or two machines but not others. A friend told me today that some 386's/486's could not run more than ONE physical hard drive ( The CD's are IDE with jumper in place) due to a BIOS limitation... which is the first I have heard of that happening... Can anybody enlighten me as to whether that is correct or has some semblance of truth or not?
