Thanks for your help. I did put the linux drive on IDE1 and in fact it 
did tried to boot, that is, it came up with &quot;L&quot;. That means the BIOS 
chip is gone?
To Randal Jarret: there is no &quot;boot protection&quot; anywhere in the BIOS 
screens.

I am kind of hesitant to start the BIOS from scratch, do I need to write 
down a sh...load of settings prior to doing that? Suppose one of them is 
the culprit, then I would end up in the same situation. There used to be 
DOS programs that would save and rewrite BIOS info, but I can't find them.

In my initial post I forgot to mention that I tried the old DOS standby
&quot;FDISK /MBR&quot;, which is supposed to rewrite the bootsector . Did do no good.
Thanks again, Cor
