Adding Multiplicator CPU Speed ABIT KT7A v1.3

[init452]

Hello guys,


I found this forum during google research for BIOS mods. It seems this is my last chance to find an solution for my ABIT KT7A. I already tried some tools, but they cannot do what I want.


During holiday I planned to do for a long time dreamed project: Retro gaming PC from 90ties to begin of 2000. This PC should include an motherboard with ISA, PCI and AGP slot.
It should run DOS, W95, W98 and WXP and include Sound Blaster ISA, 3Dfx PCI and Geforce 4 4200ti AGP.
Last important thing is: it should run between 100Mhz-1,5Ghz (at least from 300Mhz). The reason is that some games are CPU speed related.


Witch the ABIT KT7A v1.3 I found an nearly perfect and in budged motherboard. Only the lowest frequency could not be reached. The CPU multiplicator starts with 5x100 what means the lowest frequency is 500Mhz.


Is it possible an if yes could someone add multiplicator 1 – 1,5 – 2 – 2,5 – 3 – 3,5 – 4 – 4,5?
Make it sense? Or is it not possible due to mainboard HW architecture, CPU (Athlon XP 2000+) or chipset? Maybe stability issues?
Microcode update would be nice, but not strongly necessary. Its just bonus.


Thanks
