Hard drive not see in BIOS

IBM - 8177KUB
September 1, 2006 at 08:29:45
Specs: WinXP / Knoppix, P4 / 256 Megs

When I boot the machine I can not see the hard drive and when I go to the Bios I can not see it listed. However when I load Knoppix I can see and access the drive perfectly. I have tried everything from changed patch Cables to jumper settings and still can not access through normal bootup into Win XP any thoughts?

Try changing the IDE cable. If no joy,
the problem is most likely in your BIOS, since that is the thing that first recognizes the drive on boot. Try swapping the drive with a different one and see if the BIOS sees the new one. If it doesn't, try flashing the BIOS although that's no guarantee. If no joy, the only thing I can think is that the board needs to be replaced.

Is your Bios set to 'auto' detect the drives?

Is the drive larger than 137gb? It 'might' be too large for the bios to recognize.

Knoppix evidently bypasses the bios and reads/writes directly to the drive.

If your mboard is older than about 3 years old, it probably can't support the recognition of hard drives larger than 137gb because of chipset and bios limitations. If it is about two years old or so you MAY be able to update the bios so it supports seeing drives larger than 137gb if it doesn't already, but IN ANY CASE if that is not mentioned (or 48 bit LBA support)on the bios update pages, or in FAQ's about that mboard model, it can't be done. If the mboard chipset can't do it, no bios update can help, even a modern third party bios upgrade.
If your mboard can't recognize a hard drive larger than 137gb, the best thing to do is to get yourself a modern ATA PCI hard drive controller card and connect your drive to that. It will support the recognition of any hard drive size. These days they are sometimes called PATA cards (Parallel ATA)to differentiate them from SATA (Serial ATA) cards, which can usually only be used with SATA hard drives (unless they are combo ATA or PATA and SATA), which use a different data cable. You can find them on the web, or sometimes locally, for as little as $30, or less.
Most cards these days have RAID support, which normally requires two hard drives, but there are usually instructions that tell you how to install a single drive without needing to set up RAID or use two hard drives.
ST. Lab "PCI ATA 133 IDE Card" - model A-142 - it has a Silicon Image chipset. It has two IDE connectors, can support 4 drives, comes with one 80 wire data cable. It's install instructions are ok, even for a single drive.
Any card with a Silicon Image chipset is economical.
Silicon Image has further info about their chipsets and t-shooting on their web site.

Promise ones have manuals that are not so clear about how you install a single drive - see the part about RAID 0 and 1.
However some of these can be used in PCI-e slots effectively doubling the max data transfer rates.

Note than some ATA or PATA controller cards cannot support CD drives, which use ATAPI - you have to leave them connected to the mboard IDE, and that is not a problem.
The above ST Labs card does support them.
