wow...it took me a long time philo 02-13-06

I was working on a P-III-1ghz IBM Netvista today.
It's at an internet cafe...and I had loaded Vector Linux on it about 5
months ago.

For the past month or so...when I've come in...
the unit has been completely dead...but after a reboot
it seemed to work OK...at least for a while.

Anyway after I tried to reload both Vector Linux and a few other OS's
with no success (system blanked out during the install)
I took the thing hone to my shop.

After replacing virtually all components,
RAM, power supply, harddrive, net card, video card and cdrom...

sicne there was nothing else to try...
I replaced the cpu. The best I had was a celeron 533.

well that cured the problem...
I don't know (yet) if the cpu could be defective...
or if maybe it just was not quite seated properly...
or if perhaps...because of the slower cpu...the system bus was reset
from 133 - 100 mhz...anyway the thing works.
and for running Linux the C-533 is fine.


The only kicker is that upon bootup...the bios always shows the error:

"No Processor Bios Found"

but if I continue on...the machine runs fine...

when I look at the bios settings...for cpu ID...
it has just question marks for the cpu date stamp...
so I assume that the older cpu not having a date stamp
is the error the bios sees...
but there is no place in the bios to *not* check the date stamp...
and I don't want to put the P-III back in as it locks the setting to a
133 mhz bus speed...and with the C-533 the bus speed is 100mhz
so I can use 100 mhz ram...

I suppose I could just tell the cafe to leave the machine on all the
time...and if they have to reboot to just click past the bios error

Try unplugging AC, then pulling the battery for 10 minutes.
Next, you power up the system and at least enter the bios
menu then exit and save it... even if you change nothing
though presumably you'd at least set the system clock.

the sytem clock is ok...
just the cpu date stamp does not exist

Then did you not clear CMOS?
I"m suggesting, clear the cmos. That will reset the clock
so when you go into the bios and save it, you might as well
then set the clock right. Clock cannot be right if not
reset after a clear cmos.


>just the cpu date stamp does not exist

Yes so you wrote but that is not necessary to run any normal
sytem so it could be a random error with a non-obvious
solution.

the clock is fine!!!!

it just cannot pick up the cpu id date
as there is none on the older celeron
