Just for reference, looks like a Winbond  W83977EF-AW

In the cvs, I see LinuxBIOSv2/src/superio/winbond/w83977tf

I'm going to give it a shot.  Also just downloaded the chip spec pdf
files for comparison.

If things just work, you'll here.

Also for reference, my Tyan 1832DL (440bx dual cpu) has also a PC87309
(IBW* are the first three suffix letters I *think*).

I probably should have ordered a 2nd Bios Savior for my 1832, but for
now, the P2XBL 440BX motherboard is easily torn apart versus this
