Unable to boot OpenBSD on Compaq 5150

[zamboni@cs.purdue.edu (Diego Zamboni)]

Hi,

I just got my OpenBSD 2.4 CD's, and spent the weekend trying to install it on 
a Compaq 5150 I just bought (AMD K6-2 @350, 8GB IDE, 128MB, etc.). It seems to 
install correctly (I am creating a single root partition "a" plus the swap 
partition "b" for now), and even seems to install the boot block. However, 
when I reboot the machine, it goes automatically into the Windows 98 boot 
(which is also installed on a different partition). I have tried using os-bs, 
and it sets up the menu, but when I select the OpenBSD partition, it gives me 
"no operating system". The W98 part boots ok with os-bs too.

Is there something obvious I am missing? I know the above is not very clear in 
respect to the technical details, but I am not at home right now and don't 
remember all the disk settings correctly. I just wanted to through this into 
the list to see if there is something obvious I should be looking at. If I 
remember correctly, pfdisk sees the disk geometry as 972 cyls, 240 heads, 63 
sectors.

Thank you very much for any help,
--Diego
