Seen this BIOS on the "wanted" list here. [ It is from a DFI's 586ITBD (rev. A+) motherboard ]. Think that maybe a bad start point.

On DFI's website i have seen a "new" updated BIOS on http://www.dfi.com/download/BIOS/ITBD7138.ZIP
(The description is: 586ITBD ITBD7138.ZIP (116 KB) 07/13/1998 ).
It seems to solve some other problems, but docs tell nothing about big disk updates.
Also, being 1998 update it is not going to be able to cope with 60 GB disk.
On boot it prompts:"Award Modular BIOS 4.51 PG".
Does anybody know how to patch it ?
Any help appreciated.
