I have a big fat problem!

I want to use a 40GB HDD with a damn old Board (NMC)
Bios Version: 08/24/1999-i440BX-W977TF-2A69KNMCC-00
This is the lastest Bios on the NMC page, ok, there is a newer one, but it's 256 KB and i need a 128 KB Bios update.
And it's not the HDD jumper, it's set to "upper 32GB"
k, that's it, any ideas?..... please!!!
cya
