EzWinFlash error

Hi again,

I'm stuggling to set up my new SATA HDD on an AK77-600GN (see my first thread).

I've done a quick setup of XPPro on an old 4GB Quantum IDE that I had from an ancient build.
That got my system running so I downloaded updated BIOS from AOpen (with on-chip support for SATA) and tried to run it.
I get an error window saying "Failed because BIN filename error"

Googled it and found something on AOpen club forum but the link from google is dead (forum seems to be no-more!)

Any help appreciated.

Thanks, Gareth
