The listed BIOS ID for Version 433AUE25 is incomplete.
It shows up as: 41-P725-001343-00101111-101094-U880-3-H
This is manual Rev. 0.1 for the Shuttle HOT-433 Mainboard: http://www.filedropper.com/hot-433rev01
The Am5x86-P75 and Cyrix 5x86 should be added to the the CPU list.
CPU frequencies 120 and 133 MHz are also missing.
There is also a manual version that lists 160 MHz for the Am5x86-P75.
Even if not listed, 150MHz should also work (50MHz x 3).
This was my first PCI Mainbaord.
I found it on the grab table of an local computer dealer.
The BIOS socket was empty, all accessoires were missing.
No packaging, no manual, no nothing.
But only five bucks! This was little to loose to upgrade from an ISA only 486DX33 board, so I took it home.
But where to get the BIOS - I did not know brand or type designation!
I visited all computer flea markets around for weeks, and took a look at all the offered mainboards.
It took me months to find the right one.
The dealer who had it was very helpful. I visited him the next week with a small desktop PC with EPROM programmer.
He let me read the BIOS EPROM an photocopy the manual.
Unfortunately, I did not copy page 1, so the revision number of this manual is unknown.
This is the version that lists 160 MHz for Am5x86-P75: http://www.filedropper.com/hot-433revunknown
