I am going to guess on this because I do not know your system nor why it crashed.

This sounds as if you a have a PCI disk controller adapter card installed.  This could be a Promise card or another brand with an on board BIOS.   The IDE hard drives attached to these cards are detected as SCSI drives.  In many cases these boards are right next to the AGP video card and get cooked.  If the board died, or something else happened to cause the system to not look for this BIOS, you would get this type of error.  Open the computer up and look for the card, if there isn't one, then something else happened and my guess is wrong.

Another source of information is the BIOS.  Look in the setup area and you should see information on your hard drive.  Generall this is set to Auto detection but with a PCI card it may require a different setting.

Assuming that you have a PCI disk controller card, the immediate need is to get the system running to repair the damage from the crash.  You want to move the connection to your hard drives from the PCI board to the primary IDE connector on the motherboard.  You will probably have to remove a connection for an optical drive and place it on the secondary IDE port or shuffle others around.  This of course will change drive designations so once you get the computer running you can put everything back.

Good luck,

My drive is a western digital single ended ultra wide scsi-3

not an IDE.. the card that interface to the drive also has on the outside

the ports where mouse and keyboard plug to...

I tried using a similar drive and got the same scsi bios not installed message.

 

thanks for reply..

The SCSI card has it's own BIOS for managing the devices attached to it.  For the most part it works independant of the computer's BIOS. The only exception is the computer's BIOS is needed for designating the card as a bootable one.

The "BIOS not installed" message can come up if there are no devices attached to the card and the machine is booted.  In your case you have a mouse, keyboard attached and have tried a different drive.  You didn't state whether you had tried another SCSI cable?  The chances are slim that the cable would go bad, but thought I would offer that suggestion.  Otherwise I suspect that the problem lies with the card and needs to be replaced.

Interesting.  I have had bootable SCSI cards but have never seen one with a keyboard and mouse interface.  Once SCSI became Legacy hardware, I got rid of my SCSI hard drives and started saving money on IDE.

Not the first time I seen a scsi card (legacy syestem)

that has com1,com2, mouse,keyboard interface

facing the outside of a computer. and the cable connected on the inside to the drive
