SIS650 motherboard, P4 CPU, unable to install DOS6.22. When installing DOS6.22, after it gets to 10% it cannot continue. I used the method of copying external commands to copy all the files over, but it cannot format. The partition is 2G, format FAT16. Checked everything and it was normal. Finally I went into the BIOS and LOADed the factory settings, and only then could it install normally. I can’t figure it out. As I understand it, DOS should be installable under any BIOS settings, and I can’t think which specific BIOS setting would affect DOS installation. And I also can’t get back to the previous setting. Can someone give me some pointers? Thanks!
