You don't have any disk bigger than 2G, am I right ? My ASUS motherboard and most I have seen until now choose the translation based on disk size. Disk up to 2G -> 64/63. Between 2G and 4G -> 128/63, 4G and 8G -> 255/63. I've never seen a disk bigger than 8G, so I don't know how they would behave. The best option would be to ask BIOS for this info. How is the VM86 mode support going in -current ? :) Jonny -- Joao Carlos Mendes Luis jonny@gta.ufrj.br +55 21 290-4698 jonny@coppe.ufrj.br Universidade Federal do Rio de Janeiro UFRJ/COPPE/CISI PGP fingerprint: 29 C0 50 B9 B6 3E 58 F2 83 5F E3 26 BF 0F EA 67
