Shuttle HOT-591P motherboard BIOS 591PWIQH
with patch J.1 for AMD K6-2+ and K6-III+ support.

At this moment, the latest BIOS upgrade from Shuttle for the 591P is the
version 591pwiqh. This BIOS does not support the (mobile) K6-2+/III+ CPUs.
To overcome this problem, I have patched the 591pwiqh BIOS to include proper
recognition and handling of the K6-2+/III+.
I've made the following changes:
- Added detection and correct CPU Type display for K6-2+ and K6-III+
- Expanded the automatic enabling of the K6(-2/III) Write Allocation feature
to work also on the K6-2+ and K6-III+
- Expanded the K5/K6 busspeed/multiplier/CPU speed detection to work for the
K6-2+ and K6-III+ upto 600 MHz CPU speed.
In addition I've changed the Vcore Voltage Auto setting routine to prevent
the 3.2V K6 default from destroying the K6plus if Auto is selected in the
BIOS Setup. Instead, 2.2V is now supplied just as for regular K6-2/III's.
Note that the optimum Vcore Voltage for the K6-2+/III+ is 2.1V, so do not use
the Auto setting but select this voltage manually.
For all other functions, my patched BIOS is identical to the original 591pwiqh,
so you don't have to clear the CMOS if you upgrade from a 591pwiqh BIOS.
The filename of the patched BIOS is 591PJIQH.BIN and you can flash it with
AWDFLASH 7.65, like any other 591P BIOS upgrade.
Please take the usual precautions when flashing your BIOS.
Refer to Shuttle's web-site at
http://www.spacewalker.com/english/download_b … roduct=HOT-591P
for the proper flash procedure and the AWDFLASH 7.65 program.
Note that, although this patched BIOS has been tested on different HOT-591P
systems without any problems, it is provided "as is" and you use it at your
own risk.
I like to thank everybody who participated in testing this BIOS.
Jan.
