The latest BIOS upgrade from Unicore Software for the Zida 5SVA(-E) is the
version 2.0.
This BIOS does not support the (mobile) K6-2+/III+ CPUs.
To overcome this problem, I have patched this Rel 2.0 BIOS to include proper
recognition and handling of the K6-2+/III+.
I've made the following changes:
- Added detection of the K6-2+ and K6-III+ CPUs
- Expanded the CPU Type display routine for correct display of the
  AMD-K6(tm)-2+ and AMD-K6(tm)-III+ strings
- Changed the K6 Write Allocation feature to work also on the K6-2+/K6-III+
- Expanded the K5/K6 busspeed/multiplier/CPU speed detection to work for the
  K6-2+ and K6-III+ as well.

For all other functions, my patched BIOS is identical to the original Rel 2.0,
so you don't have to clear the CMOS if you upgrade from this BIOS.

The filename of the patched BIOS is 5SVA20J1.BIN and you can flash it with
the flash program you normally use to flash a 5SVA(-E) BIOS upgrade.
Please take the usual precautions when flashing your BIOS.

Note that, although this patched BIOS has been tested on a 5SVA(-E) system
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.
