The latest BIOS update I have is:

JT586IV4 MAY,17.(96) UMC8669 ONLY. VER:12
04/11/96-SiS-5511-5513-2A5IDJ69C-00

There is no way to patch it or make it support large HDDs. Drive overlay software is your only hope.

There's a BETA BIOS too:
05/09/96-SiS-5511-5513-2A5IDJ69C-00
(2a5idj69) EVALUATION ROM - NOT FOR SALE

It's Award v4.51 but still up to 8.4GB only.

...but the official BIOS message says May 17, making it look somewhat newer.
