I've wiped and reinstalled DOS and OS/2 several times. I was hoping to use the OS/2 Bootmanager to control which os comes up. Someone posted a note a few weeks back explaining that the BIOS does geometry translation on drives larger than about 300MB (1024 cylanders) which confuses things. The thing to do is use your CMOS setup software to configure the drive for its real geometry. Then DOS only sees the first 1024 cyl. of the disk, and you can put 386BSD at the end. That's where I am now, but haven't had time to reinstall BSD (last delay was that my memory died, and I had to wait for new SIMMS which arrived today). I have a Maxtor LXA535A, and downloaded their low-level format program and ran it on my disk just to make sure things were ok after changing the BIOS settings. This is a rather confusing procedure, esp. since there are no good partitioning tools that recognize the operating systems involved.
