Hello, I have the following IBM Personal Computer 340 I am currently restoring/upgrading:
Machine Type: 6560-17A
Surepath BIOS Flash Revision Level LXKT20AUS
BIOS Date: 07/21/96
System Board Identifier: 0YVTGL28S25
I'm trying to replace the original Intel Pentium 100 CPU with an Intel Pentium 200 CPU (non-MMX of course).
- The FSB jumpers can be set for 50MHz, 60MHZ, or 66MHz
--- I set them for 66MHZ
- The multiplier jumpers can be set for 1.5x, 2.0x, 2.5x, and 3.0x
--- I set them for 3.0x
- The CPU voltage jumper can be set for 3.3V or 3.52V
--- I set it for 3.3V
When I install the 200MHz CPU it is still reported at 100MHz? I played the binary shuffle with the multipliers but that only resulted in the CPU being reported as 0MHz at times or 100MHz, nothing else.
I installed an Intel Pentium 133MHz CPU (66MHZ FSB, 2.0x) and that works fine. I don't currently have a 166MHz CPU laying around to test.
I don't understand why 66MHz with a multiplier of 3.0x is not working? I looked around for BIOS updates but these seem non-existent (I would much appreciate if someone could point me to a location to find IBM BIOS updates).
Is there something I'm missing with this model/series of IBM systems?
Any help would be appreciated. Thank you.
