Hi,
	Well I'm back at my desk and I rebooted the infamouse Proliant 
2500 with SMART2/p raid card and RH 6.1.
	I say rebooted but in fact it comes up with "non-system disk" 
try again. Putting the floppy disk for that box in the floppy disk drive 
 will get it working fine it just will not boot from the hard disk.

	so, the raid device is listed as    /dev/ida0
configured as a raid5 setup that is 4 physical 4Gb disks showing 
up as 2 logical disks.

	Using LINUX to look at each drive I get :

	ida/c0d0: blksz=512 nr_blks=16434495

	ida/c0d1: blksz=512  nr_blks= 8720160

using LINUX fdisk for
 ida/c0do: ida/c0d0p1, ida/c0d0p2 < ida/c0d0p5 through to 
ida/c0d0p9

thislast message by the way is as printed to screen including the < 
sign.
In lilo.conf I tried leaving out the P1 on the first disk to see if it 
would default to MBR no luck, tried putting it back no luck there 
either.

	From within LINUX tried DOS fdisk /mbr got the message could 
not open mbr, (I did this to try clearing the mbr to copy it back from 
the boot.0x00 file). I tried booting into DOS via a dos boot floppy 
and using fdisk but because of the raid array it cannot find the fixed 
disks.

	Any ideas, comments (appart from is he thick or what <BG>) 
ways of getting this infamouse box rolling.
