 Hello Ted,

 I just did a minimum install but I had to do it twice. I had
 no additional costs so I don't mind :-).

 I did a bios upgrade but it didn't change anything exept that FreeBSD
 4.3 needs some seconds before continuing to boot when power managhement
 is enabled. Version 4.4 puts the laptop in a kind of dangling mode which
 means the screen is blank the hd is down but the computer is not turned off
 properly.

 There is no change when I try this. BTW, the file is called /boot/loader.rc .

 It is a Gericom Laptop from the 5xC Series. My version was sold only in
 MediaMarkt Stores and is labeled as "Network" (which was their own branding 
 of computers).
 On boot screen it prints out:
 SystemSoft Bios v 1.17.01
 In the bios it shows up a version:
 1.00.3 Date: 10/22/97 (which I doubt)
 
 Bye and hth again,
