Booting off a SCSI Disk Controller??
Posted on 2004-11-10
OK .. i had a Windows NT server that has just died on me and i have now replaced it. The two Hard Disk Drives in the dead server are SCSI disks and one of them contains an operating system (Windows NT) and is a boot disk. The other SCSI disk is just a data disc I have transferred these disks to another system that has windows XP with standard normal IDE drives. When i boot up in windows xp i can see the drives (and relevant partitions) in "My Computer" of the Windows XP pc. But i would like to be able to boot from the disk that has the Windows NT Server on it.
In the bios of this particular pc that i am using there is an option to change the boot sequence from HDD to SCSI which is what i have done. But upon bootup it doesn't recognise either of the scsi disks and boot halts asking me to insert a system disk etc. (As i have totally disabled the IDE HDD from the bootup sequence. eg. When the boot sequence is ... floppy, scsi, hdd, cdrom .. the windows xp operating system boots up. But when the boot sequence is .. floppy, scsi, cdrom .. the bootup stops with the error message "replace system disk" or words to that effect, meaning it doesn't recognise either of the scsi disks in there).
On bootup i have tried to press both Ctrl+A & Ctrl+C to see if there is a SCSI bios program that i may be able to get into but to no avail. I think what is happening is that the SCSI device drivers aren't being loaded and hence the SCSI devices cannot be "seen" upon boot up. So can anyone advise me how i maybe able to get these devices to boot up?? The chip on the card says AIC-7880p and on the card itself it says M11E Combo Card (plus alot of other numbers and letters).
Although the BIOS has the option in the boot sequence to boot from a SCSI disk clearly the BIOS has nothing to do with actually being able to see the SCSI disk in the first place. I "think"??? i need to run some sort of floppy boot disc to load the SCSI device drivers first so that the SCSI disks can be "seen" and once the SCSI disk can be seen the pc will proceed to boot from the SCSI drive loading the Windows NT Network Operating System. Any ideas on how i do this would be greatly appreciated.
