access to BIOS of DECpc

Hi all, thanks for all the responses, I have some leads now. Here is a report what I tried so far. Searching the Internet, I found the setup files set320p and pwr320p for the DECpc 320P. Alas, the setup allows several items to be configured, but the hard disk is not one of them! Next, I found Ontrack DiskManager versions for IBM and for Microscience, but the IBM version stops because it does not detect a hard disk of their brand. BTW, my 2.5" hard disk is from HP, type C2965A. The Microscience version allows 7 different types to be set, but up till now I did not get satisfactory results. I can get to 50 Mb, but compared to the original hard disk (40Mb) that is not much gain, especially when you think that the C2965A is 420 Mb ...! I also have the version from Western Digital, EZ-Drive (Data Lifeguard) but this version also stops because the disk is not from WD. Not yet tried is a version from Fujitsu, and the version I received from Pete (thanks Pete!). I guess it's clear what I will be doing this weekend :-) thanks for all the help and advice, - Henk, PA8PDP.
