I did some "research" but I'm getting the feeling that C= programmed the
BIOS to look for a particular drive and no other one.

My manual says that all info (text, program ???) to add an HD to a PC is
supplied with the new HD. So my question is: does anyone on the list have
this "info" ?


After writing the above I suddenly remembered that the PC10/20 has an
onboard clock. The Motorola-RTC used from 286's on has RAM onboard. Some
centuries ago I studied the one's used on XT's, mostly OKI and MC57???. And
I vaguely remember that they have RAM as well, but I'm not sure.

Groetjes, Ruud
