Further update. The error code is as follows, after the pc boots and registers the raid array the following is displayed.
"Bad md_map in ll_rw_block"
"EXT2-fs: unable to read superblock"
"isofs_read_super: bread failed, dev=09:01, iso_blknum=16,block=32"
"Kernal panic: VFS: Unable to mount root fs on 09:01"
I've tried playing around with the bios settings, mainly due to the fact that I'm using a Promise ata100 pci add on card and thought it might have somthing to do with plug-n-play or irq's, all to no avail. My next step is to reinsatll onto the standard onboard ide and see what happens. Thanks for your info at this stage,
Karl
