I am trying to help out a friend here that has problems installing 2.0R on an enhanced IDE drive. I hope to find an answer as his company wants to start using FreeBSD. I am afraid they will go on with Linux otherwise. In his BIOS setup, he entered 1048 cylinders, 16 heads and 63 sectors/track IDE_CONF reports: Cyl Hds S/T Bios reports 524 32 63 Controller 1048 16 63 before reset ,, ,, ,, ,, after reset The strange thing is the fact that the Bios reports something that is different from its own setup!? The bios is an AMI one (on a P90 board). The settings now behave like: Cyl Hds S/T After Msdos fdisk/mbr, FreeBSS reports: 1028 16 63 After making a 50Meg Dos partition with fdisk, FreeBSD reports: 524 32 63 (plus a notice it cant handle 32 heads). So I just dont know what settings to use. I'd say 524/32/63 but that's explicitly forbidden. I hacked a new wd.c that allows it, but that hasnt been tested yet. (btw: what happened to the ATA docs in /sys/i386/doc?) Any other options? -Guido
