You are totally right! I did change the SCSI to Primary & secondary. It is 
the only way the computer is able to detect the 3 scsi HDs. if I set it off 
(as default), it does not detect the hd.
I am pretty confused! Should I need to set the scsi to  SCSI to "Primary & 
secondary" (if just  set 'secondary only' only CD rom will be detected)?

last night, I replace another scsi hd (scsi#0, linux was installed on this, 
save this one for later play with Grub) and reinstall RH 9.0. Here is what 
happened:

1. set scsi Primary & secondary on bios,  turn on the box. at the final step 
of bios, it prompt me with this,

Alert! cover was previous removed
  strike the F1 key to continue, F2 to run setup utility.

2. after I press F1, it shows the Grub GUI with 2 options
vmlinux-2.4.0.18slm ...
vmlinux-2.4.0.18 ...
it don't work if I select the first one (vmlinux-2.4.0.18slm ...), and the 
2nd works.
is the first option  the old grub boot information?

How do I get rid of pressing F1 and skip choice of 2nd option from grub GUI, 
just boot the linux?

Learned the grub syntex from the new installation, will put the original 
scsi back and  try this tonight! thanks
