Notes for P6BXT-A+'s unofficial AwardBIOS v6.00PG BIOS

Also internal_name corrections
BIOSes to Compaq Compaq ProSignia S31x, which is renamed into ECS P6BXT-A+.

Also unblock Cyrix CPUs as well as unofficial 6.00PG BIOS supports them.
Also slightly changed the maximum voltage bus to 124MHz per unofficial v6.00 BIOS, corrected the BIOS name per the BIOS screen on that BIOS, and added the author credit.

Also lowered the minimum memory on LG IBM MS-6106 to 8mb.

Wait a moment, @MaxwellS04! I already made pull request #6338 last Monday.

And also, why don't you rename the folders and the internal names from "prosignias31x" and "vei8" to "p6bxtap" and "6110zu" respectively in the roms/machines directory?

Considering the history, we're much more likely to accept maxwell's pr.

@MaxwellS04 Please keep the internal names instact and make sure the default BIOS is the one currently used and its internal name the same as that of the machine (because we use the BIOS' internal name for the NVR and Flash BIN). This ensures proper configuration migration without breaking existing configurations.

I have done now.
