The above partition table is correct. I have no problem with linux. windoze 95 also works. When I go to change the Award bios, for both hda & hdb, the CHS is 1024, 255, 63. When I try to change the cylinders to agree with the above table, the bios will not accept the correct values of 1653 $ 2434 for hda & hdb resp. The bios also indicates the maximum LBA values for hda & hdb as 13000 MEG & 20000 MEG which are correct. This bios always recognized automatically the hd geometry when I switched hd's on my slave which is a removable caddy from the front. Now it doesn't do that. All this problem started when I tried to install Corel Linux 1.2 evaluation cd. I had empty space on my hdb13 and it formatted the partition. It also changed hda to add a boot partition hda6 and renamed all my partitions in hda. I know that you should not mix linux fdisk and PM but I didn't think it would cause PM not working. The main question is how do you change the bios to accept the right values. TIA jozien
