k7s8x r3
#1
Hi there...
I got one ASRock K7S8X R3.0 with latest BIOS P2.60.  The board had some low end CPU such as Duron 800. but this CPU wrnt to another board. Recently, I bought an AMD Athlon XP 2600+. The black sticker on the CPU clearly says AXDA2600DKV4D however there's something wrong with the CPU or the motherboard.
The board has 2 sets of jumpers. One for FSB and the other for multiplier. Multiplier block has no jumper caps installed, the manual says it cames with none. The FSB block has 2x3 pins and we can set 200/266/333/400 mhz. Howerver the cpu refuses to work at 166MHZ(333MHZ DDR). When the cpu arrived, it didn't want to enter the cpu socket but with some wiggling, I managed to install the cpu without bending any pins. I also cleaned any old paste.
The CPU seems to like 100 and 133 but not 166/200. If I set 166 via jumpers, it goes down to 100 or presents and erractic behavious like running at 166 but it loses this "setting" after a poweroff/on.
I also tried 200mhz, but the cpu goes to 133 and very rare case I seen it run at 200x11.5 ... and showing 2300mhz and getting very hot.
I don't know what's going on. Probably the cpu has some problem. Maybe some internal connection core-pins or those components soldered at top being flacky.
CPU upgrade site says the cpu should work but the ASRock site is a bit vaugh. There are at least 2 models of 2600+ and mine is Barton.
I wanted to try to inject the BIOS with latest microcode patches, for start. Then I want also to color mod the BIOS setup screen... I more adept of white on black colors. I want also, to inject an option rom like Plop boot manager so I can boot to usb. Current USB boot is crap and doesn't work with anything.
So far I have been testing with some popular mod tools like mmtool which doesn't seem to recognize the bios file... and also amibcp for windows that also doesn't seem to like the file. AMIBCP 7.60 for DOS does like the BIOS file but... I can't seem to find where the microcode module is nor find the options to remove/inject modules.
The BIOS screen at top says it's AMIBIOS 3.31a.
Any help appreciated.
