    Question Bios

    As many of you know...I have been trying to get my Compaq Deskpro 590 back up and running for several months now.

    (If you want to review what has happened so far, search for the threads "A Word of Wisdom from DavidP" and "Networking")

    Anyways, I have been playing with the BIOS and am puzzled by something.

    When I go in to the place where I can select the drives availble, it tells me that I have a floppy drive and my hard drive, and it says my CD ROM is non existant, of course that is nothing new. It has been doing that for some time now.

    So recently I clicked on the "Advanced" button and it took me to a screen where I could specify the IRQ's for the Primary and Secondary drive controllers.

    Under the spot of Primary, it had my hard drive, but under the Secondary spot, it said "Disabled".

    So I thought that was the problem, the Secondary drive controller, where my CDROM drive was located, was disabled. So then I started trying every IRQ on the list, but none of them worked. In fact, every time I went back into BIOS to change the IRQ again, it said "Disabled" again, as if I had never changed it in the first place. But I know I did change it, and I know the setting was saved when I changed it, because it had asked me to save the settings when I exited BIOS every time.

    So why exactly is it going back to "Disabled" every time I reboot the computer? I have tried every IRQ and none will work...the BIOS just keeps switching the controller back to disabled....

    Does your MB have a secondary IDE contoller? (or just the BIOS thinks you might have one)

    I have a MB that has RAID on some versions, has RAID settings in BIOS but that does not mean I can turn it on.

    Yes it has a secondary IDE controller, otherwise I would never have been able to hook the CDROM to the controller that says, "Secondary" and use it before the incident 3 months ago (which you can read about in "A Word of Wisdom from DavidP")

    sounds like:

    a) your bios needs to be flashed with a newer version
    b) your secondary ide controller is a piece of s**t

    send it back and get it replaced if the second is true...

    also... are you sure you're hooking the cable up the right way? I know, stupid question, but I've done it accidentally... meaning, getting the right end in the controller... I'm sure you've checked and double checked that tho..

    yeah its the right way...ive checked that...

    i also have been using the newest version of the BIOS...i downloaded it from the Compaq web site....

    one thing though...it told me to put the BIOS on a diskette and boot to the diskette...but then after I change the settings and leave the BIOS, I dont boot to that diskette anymore...

    Do you think the settings are saved on the diskette and not the computer for some reason? But why would it get the computer's settings...and then not save the settings to the computer?

    did you follow the directions exactly?

    I've only flashed one BIOS in my life... and if I remember correctly, I had to boot to the floppy 2 or 3 times before it finished.

    Is the CD's jumpers set as (secondary) slave or master?

    Try swapping the HD and CD cables and see if the HD stops working and the CD starts (is onboard IDE at fault if does)

    If it is the IDE ctrl, put both on one cable, ensureing CD is slave.

    Oh...that is one more problem.

    I tried swapping the CD and HD ide cables about a week ago...now it refuses to boot...even to a floppy...

    It will read the floppy...and almost boot to it...but in the end it will just sit there with the cursor blinking and do nothing...

    Oh...and this particular CDROM drive does not have a slave/master switch. But that is not the problem...because I have tried CDROMs that do have slave/master switches and they dont work either...and they were set to slave...

    When you swapped the drives did you change the settings in the BIOS?

    Try two good HD's after detecting them in the BIOS. I also had a problem with Compac's not allowing user defined drives. That is if the drives size (heads, sectors ect) was not in the list in the BIOS it could not be installed.

    Does the CD work in other PC's?

    it sounds to me like your motherboard took a hit... you might want to start looking for a new one...
