Well, the BIOS gives you three options: CHS : 38792 cyl / 16 heads / 63 sectors = 39,102,336 sectors LBA : 2434 cyl / 255 heads / 63 sectors = 39,102,210 sectors Large: 2586 cyl / 240 heads / 63 sectors = 39,100,320 sectors Auto In fact, if configured as "Auto", it chooses to go "LBA", as stated during the final boot process. I wonder if FreeBSD (or the boot0 loader) gets confused, since the number of heads in LBA (255) is not in the form m * (2^n), so it cannot guess the real geometry of the HD. Also, I wonder if setting the option "Large" mode could be of some help (and if it will work with MS Win98). Of course, I guess I'll have to repartition the disk and reinstall everything if going this way. By the way, a strange thing happened to me the first time I booted the system and tried to set the Win98 partition with its FDISK tool: I forced the LBA mode in the BIOS, and the FDISK stated that the HD was 8GB large. So I set the "Auto" option, it booted LBA again, but this time the FDISK saw the real size (about 20GB). Any hint, please? TIA.
