I had to replace the 500 mbyte hard drive in my Toshiba Portage T3400CT when a baggage gorilla dropped it. The smallest drive I could find these days was 2GB, and the Toshiba BIOS couldn't see beyond 800 mbytes. I used an OnTrack-like product downloaded from the Fujitsu web site. When it starts, it gives you an option (catch it before a countdown timer expires) to boot without it loading BIOS extensions that otherwise replace the ROM-based disk BIOS routines. They think the reason you'd want to not load the extensions is if you're booting from a floppy, but what do they know? So, I put all four fdisk partitions to work. The first two were rather small, both fitting in the first 800meg. One was the MS-DOS "C:\" drive and the other was a FreeBSD root. The other were an MS-DOS "D:\" drive (accessable from DOS only with the BIOS extensions loaded) and the other was the rest of the drive, mounted as /usr under FreeBSD. So, at boot time, if allowed to go normally, the BIOS extensions are loaded (from blocks 3->63, I believe) and Windows 95 boots up thinking it has 2 drives totalling about a gigabyte. If I slap it during the countdown timer, it doesn't load the extensions and the ROM-BIOS boots FreeBSD which also thinks it has two drives totalling about a gigabyte. Once I figured out where all the pieces had to go and in what order, it isn't bad at all to use. -crl -- Chad R.
