Thanks to Tanguy for informing me that Abit has released the final version of the BIOS PV for the BE6:

Abit has posted the final version of the BIOS PV for the Abit BE6.

The link isn´t on the website yet, but the file is already on their FTP: ftp://ftp.abit.com.tw/pub/bios/be6/be6pv.exe
The drivers 1.25 for the UDMA66 controller that corresponds to the new BIOS (the HP366 BIOS is also updated to the version 1.25) is still in the beta section at: ftp://ftp.abit.com.tw/pub/beta/be6/drivers

I would recommand to wait for the description of the BIOS on Abit´s website though...
From what I heard/read this new BIOS and these new drivers should fix the power management problems under Win2k.
