Hello. I want to thank the people here for offering me advise about building a machine with DOS 6/Win 311.
I have been struggling with understanding ways to get CHS addressing working on two of my PCs.
I am realizing that the problem is in configuration schemes that existed before the 1996 BIOS Boot specification.
You had to know the CHS values of your disk, but just scrounging up this information from common sources was thwarted by hard drive auto detection.
So here I could use some advice because although I own an Ultra ATA 33 interface that auto configures CHS values; I want to configure CHS values manually on the behalf of BIOS.
I also have an interface with out an option ROM BIOS chip. It is non-PnP and PCI local bus. It permits auto detect of disks by BIOS but the CHS values that they detect are not usable for booting.
Any ideas on what to do if you want to dicern the correct CHS addressing for booting an early 90s PC?
