Hi all.
This site is awesome. I've done the 770z upgrade to a 500mhz PIII coppermine-core processor. Right now I've got 3 128M PC100 memory in all 3 slots. That mainboard slot really is "hard to get to" -but not really that difficult. It's just time and following the excellent maintenance manual step-by-step.
I was amazed that there was a lot of junk in there. I had used this TP for a year before I did the upgrade and it worked fine. When I opened up the beast I found a loose/free-range jumper thingie floating around under the processor. Don't see where any jumpers were missing. I think this must have been something that the original Candidian tech dropped in there when he/she assembled this machine. When I pulled off the mainboard to get to the "hard to get to" memory slot I found a tiny molex connector like the one that the microphone wires are connected with to the MB just floating around under there too. Needless to say, I didn't put those two parts back in. I don't think that floating junk in there is necessary to the operation of the laptop.
Booted with the 127 error so I did the hex editor with the help of a friend and figured out to switch 00 to 08 at location 20.
Now it boots cleanly to winXP and it is running fine. I can tell a big difference between now and before running XP. This 770z has the 14.1" screen with the 1024 x 768 resolution. I hope to replace the screen and vid card from another TP on eBay. I have a non-upgraded 770z with the 13.7 screen that I may upgrade later and going back to the low-res screen is not a goodness. Big difference in my opinion.
Sandra says that the L2 cache is enabled but I'm not running anything to turn it on. I thought the BIOS change disabled the cache so it could boot. Do I still need to turn this back on to get the max performance of this processor? Is Sandra wrong? -or am I reading it wrong?
So far I saw one weird video phenomenon when I booted but it went away and I've never seen it again after about 30 boots. I'm going to be using this machine as my daily driver so I'm going to see how well it works in the long-term. I've been using these 2 770z's for the past 2 years as my daily driver and basically the only thing showing any wear are the keyboards. Rock solid units the 770's are.
I can't wait to see how the PIII holds up in this unit. So far the temps have not been too high and rarely get over 65C according to Mobmeter.
