I've looked at the dual boot notes in a number of different places this was what led me to wipe and repartition the drives in the first place (under the assumption that on a blank drive, FC2 would be smart enough to create whatever partition structure was valid for itself... apparently not). - The Maxtor utility shows both drives as 39703/16/63 - The BIOS autodetects both drives as 39703/16/63 and shows that LBA is enabled Here's where things get odd... if I force the CHS on the kernel command line I get the following... [root@server1 var]# cat hda/geometry physical 39703/16/63 logical 39703/16/63 [root@server1 var]# cat hdc/geometry physical 39703/16/63 logical 39703/16/63 But if I don't force it I get this... [root@server1 var]# cat /proc/ide/hda/geometry physical 39703/16/63 logical 2491/255/63 [root@server1 var]# cat /proc/ide/hdc/geometry physical 39703/16/63 logical 39703/16/63 Note the difference in logical parameters on hda only. Interesting I think, so I pulled the drives and swapped them around (primary to secondary, secondary to primary controller), fully expecting hdc to show up as 2491/255/63... but it didn't, hda did. I tried... [root@server1 sbin]# ./sfdisk -d /dev/hda | ./sfdisk --no-reread -H255 /dev/hda But I get... Disk /dev/hda: 2491 cylinders, 255 heads, 63 sectors/track Old situation: Warning: The partition table looks like it was made for C/H/S=*/16/63 (instead of 2491/255/63). For this listing I'll assume that geometry. Units = cylinders of 516096 bytes, blocks of 1024 bytes, counting from 0 Does this mean that I need to zero fill hda again and partition it as 2491/16/63 and leave hdc as 39703/16/63 to make FC2 happy? I don't mind repartitioning again, but how can I be 100% sure of what geometry FC2 is going to be looking for so that it'll be happy with the result. >>>>> Mike <<<<<
