I just bought a new pentium pro 200 computer and I tried to install BSDI. 
I tried to boot from the install disk and it gives me this error:

Read error on block 16 of unit 0
Error 4: sector was not found. Retrying...

and after a while it says generic I/O error and it stops reading the disk.
It gives me this kind of reading errors even if I try to install Solaris,
linux or Freebsd! 

On linux The kernel boots fine and then I have to put the root disk and 
press return. Then it gives me this error:

end_request: I/O error, dev 02:1c, sector 2
RAMDISK: I/O error while looking for super block

Now comes the weird part. The computer works fine if I install OS/2 or any
kind of MS Windows and I get no errors! It probably has to do with the
operating system starting at sector 16. 

The motherboard is an Intel with the 450KX chipset, an Adaptec 2940
controller, Trident SVGA and nothing else.  I tried different floppy
drives and still the same. I tried all different BIOS settings and still
the same. I know that the disks are fine since they boot on other pentium
systems. I also tried to install an ISA floppy controller but the
motherboard doesn't recognize it. Pin 5 is missing on the floppy interface
(on the motherboard, it's used as a key), something that I have never seen
before but I don't thing that the floppy drive needs it (It's only GND if I
remember correctly). 

I cannot call the company from where I bought the computer because they 
test with windows and I have to admit that windows works great!

Anyone has any ideas?

Thanks for any help
