BIOS Updates forum

Maybe so. But I just got a used T23 anyway. I think I'll be selling the 600E for parts.

Sure, it's 2645-55U.
I tried the clock generator mod, I posted about it here.

Hi, I am new to this wonderful forum. Currently I am planning to upgrade my Thinkpad 600E PII 366MHZ's processor to PIII. I found one PIII 1.13 GHZ that's pulled from a ibm r31 on ebay: http://cgi.ebay.com/pentium-3-1-13-ghz-laptop-processor-ibm-r31_W0QQitemZ150064350672QQihZ005QQcategoryZ86715QQss...

Sorry to keep answering my own questions. :P I'm guessing that it's not running at 500mhz simply because I haven't done the speedstep mod yet. :mrgreen: :EDIT: It still is not booting to the higher speed even with the mod finished. I see the bus speed is at 65.80mhz and .6580x500 = 329, which is exa...

I tried taking one of my 128mb sticks of ram out and was able to change it then. I then shut down and reinstalled the stick of ram and did the bios change again, this time with the ram. Powerleap indicates that this is running at only 328, 329, or 330mhz, when it's supposed to be a 500mhz CPU. Any t...

Ok, great. I just got the PIII board and I installed in my 600E. I get the 127 error, but I can't seem to get to the bios setup by pressing F1. I can, however get to the setup by clicking on the test button when the error 00127 come up. I seems to freeze before I can get to the hex editor, though. I...

Thanks for clearing that up! Note: Some people have experienced instability after upgrading to PIII CPUs caused by the onboard RAM. When you install a PIII CPU you automatically increase the FSB to 100MHz which can be too high for the 66MHz specification memory. You can disable it in the same manner...

Ok, so I should change 00 to 08 instead of changing 00 to 0A, right? I understand that Powerleap has been used to enable L2 cache once the computer has booted, does this seem like the best method to use? Also, I'm confused as to which byte enables/disables the onboard RAM. I'd like to know in case i...

Hey everyone. I recently bought a 500mhz PIII for my 600E (2645-55U) and am awaiting its arrival in the mail. So I just updated the bios to what I believe is the latest version (IHET47WW) to get it ready for the upgrade and possible mods. Apparently I'm supposed to change byte 20 from 02 to 0A in th...
