I just got a 40 MB drive to replace one which had crashed. Can I partition it into two logical drives and run DOS in one and MINIX in the other? If so, practically speaking how much disk does MINIX require -- would a 10 MB partition be too small to be useful? A related question -- I am using a replacement mothernboard from Wavemate, Inc. It has an 80286 with XT slots and Wavemate's own BIOS -- has anyone had compatibiliity problems with their BIOS and Minix? Thanks, Larry -------

A MINIX partition can go anywhere, but fsck will bomb unless MINIX is in the first 32M. The wini device drivers for MINIX do not have this bug. I.e. without fixing some software, you really have a 32Meg disk. Solutions: DOS - don't even try, just put it in the first 32M. MINIX #1: Fix the physio routine in fsck to take a 16-bit partition offset instead of a 16-bit absolute sector number as an argument. MINIX #2: Fix fsck to run under MINIX instead of under BIOS. A version of fsck to do this has been posted to the net. You cannot boot MINIX with the hard disk as a root filesystem and expect to check it. Boot with the standard RAM root filesystem to check the hard disk. -- Stuart D. Gathman <stuart@bms-at.uucp> <..!{vrdxhq|dgis}!bms-at!stuart>
