My next post is about TP770X. I hope this is helpful for other 770X users.
My TP770X actually works with PIII-500.
However, this CPU upgrade caused a lot of minor problems. Here is the list of
the problems and the solution for each I came up with.
1: After upgrading the CPU to PIII-500, the FSB is changed to 100MHz, which kills
the PC66-64MB DIMM installed in default. So I removed it and installed two of
2: After doing this upgrade, memory check in Easy-setup issues an error.
I just ignore it.
3: After doing this upgrade, my TP770X can no longer boot from CDROM.
So I needed to first install MSDOS, make it recognize the CDROM and launch
the OS installer from MSDOS prompt.
4: After doing this upgrade, the boot up process is trapped with 127 error twice.
In order to boot the OS, I first need to push ESC in the first error, then push F1
in the next error and finally the OS boots up. (This is the famous 'keys on boot'.)
5: After doing this upgrade, the L2-cache is not enabled by the bios. So I enable
the L2 cache in after booting up Windows by using either,
'Powerleap CPU Control Panel'
http://www.powerleap.ca/Products/CPU%20 ... 0Panel.htm
or 'Cache Utility'
http://powerleap.custhelp.com/cgi-bin/p ... 1049321145
6: These Powerleap utilities cannot be used for DOS/Linux environment. So when I
want to boot up Linux, I first boot up freedos (or any other DOS), enable the L2 cache
by using 'cache-enabler 1.20'
and load the Linux kernel using 'loadlin'
7: After doing this upgrade, the initialization of the video card sometimes fails and the
display is messed up. In this case, I need to reboot the OS until the initialization
is successfully completed. Once the system boots up successfully, I usually don't
turn off the system, but just go to Stand-by mode which does not require
re-initialization of the video chip. Then the system wakes up just fine.
8: Although I was successful in this CPU upgrade, I have seen many people saying
that TP770X system board cannot take PIII. So this CPU upgrade on a TP770X is
not guaranteed to succeed. TP770Z should have no problem in this upgrade.
