Hello all,

Can anyone modify the BIOS of this motherboard for me to support 128GB hard disk with UDMA fix?

I found a patched one here but sadly, the UDMA doesn't work with it:

Code: Select all

=> Patcher can make support of big HDD (up to 137 Gb) with fixing "UDMA"-problem (HDD UDMA66/100/133 on only_UDMA33 MB)

Code: Select all

3. UDMA mode limitation 
In the older Award BIOSes was the HDD set to highest supported mode, it was not problem when only UDMA33 HDDs were produced, but later problem arised: HDD was programmed to e.g. 66 MHz and chipset maximum was 33 MHz, the result was unreliable operation. There are some solutions, switch off UDMA in BIOS setup at all, or use special program supplied by HDD manufacturer and switch off ATA/66 support. Better way is to implement this directly into the BIOS code. FYI: 
UDMA mode 2 = ATA/33 
UDMA mode 4 = ATA/66 
UDMA mode 5 = ATA/100 
UDMA mode 6 = ATA/133

What brand/model harddisk are you using, what firmware release is it and what kind of brand/model cable are you using?

I use Maxtor DiamondMax Plus 10/21 80GB with 40-pin IDE cable.
Both work great on patched ATC-5000/5050

I'll see if I can find any other patched bioses. Somehow I have a feeling I have seen this board before...

Thank you, fingers crossed

Indeed UDMA will not work with that IDE chip because it was never designed for that. The 430TX chipset DOES indeed support UDMA but the Prime 3C IDE does not.
