I got a SCSI U320 1-CH controller: HP374654-B21 (LSI chipset) and 3 SCSI hard drives Fujitsu MAT3073NP 73.5G (initially dreaming of hardware RAID5, gave up long since on account of aacraid driver issues with another controller), on a Dell Dimension 8300, 2G ram, A07 bios, dedicated to Linux.
Installing Sarge from the 2-DVD set, manually partitioned all three hard drives sda,sdb,sdc. Installed base system, came to GRUB install said yes to the MBR install suggestion (Though I noticed the response was it was going to put it in hd0, I thought it might be sd0 in this setup, I don't have any (other) IDE hard drive just a DVD-ROM & a CD-RW). On sda the first partitions are:
#1 /boot 1G
#2 / 1G
...etc

After reboot and ejection of the DVD, I can't past beyond the: 'strike F1 to retry boot, F2 for setup utility'. I have no clue, as to what's going on. Any help would be very appreciated, thanks

Thanks for the reply. HP tech support suggested there may be a fundamental problem in that the Dimension 8300 BIOS may not be recognizing the controller as a bootable device, because I am able to see the drives during the install & partition them but during the attempted boot there is no device whatsoever that shows up on the screen, just the 'strike F1 to retry boot, F2 for setup utility'. I am skeptical a bit, but will investigate it before anything else as it would be a showstopper.

Later: I tried to install Windows just to independently confirm if I can boot some OS with this SCSI controller. Didn't work either. I provided a driver from HP (meant for Windowserver 2003 to be precise, but XP was quite happy to use it) with F6 during install, installed it on a newly created C partition, and after the first phase of the install (and continue=ENTER), complained about not seeing any hard drives on the system! Called Dell support, they said there is no limitation whatsoever in this BIOS but I never got to talk to a real techinal guy, they have those intermediaries going back & forth when they don't know what to say... go figure

It turned out as I feared. I had to return the HP (LSI Logic) controller HP374654-B21.
I thought maybe an older U160 plain vanilla controller might have a better chance, indeed, I got an Adaptec 29160 and the BIOS was happy to recognize it at last.
