OK people,

I have a TP770 in which i swapped out the P200MMX and put iin a PII 266. I got tired of the error code 192 and needing to hit esc and F1 to get past it. I went into the config bios and did a Ctrl-D and possibly messed up a value on the first page. Now when i turn it on and get error 192, i can't get past it with an esc and F1 trick anymore. it just keeps coming up with the two error screens. Can anyone advise me a solution to get the BIOS back to a good state? maybe a jpg photo of the ctrl-D screen showing the correct values, or some reset proceedure. I really screwed it up now...

Thanks for your help,

Joe

p.s. - it is a 9548-40U

If you can still get into your BIOS/EZ-Config by pressing and holding F1 on bootup, then I think you can use the "Initialize" function and this will reset the BIOS to its default/factory settings (I think!).

No, that doesn't help. Does anyone know a way to get the CMOS settings back to default? Would removing the battery do it? If so, which one, the watch style accessible under the bottom cover, or the yellow blister pack one with the connector that you have to remove the keyboard to get to?

Any advice would be really helpful...

Thanks

I'm not familiar with your model (mine are 600, 600x) but most newere machines have a hidden reset switch

HAVE YOU DOWNLOADED THE hardware manual?

If you pull the CMOS battery(the yellow one under the memory cover), it will revert to the BIOS "Enter correct Date/Time" screen on startup, once you set the time/date, it will not give you an opportunity to do any other changes

However, once the CMOS battery has been pulled, -it may- clear the other settings and allow it to boot correctly.

The yellow battery is the "standby battery" and requires removal of the keyboard. The "backup battery" is silver colored about the size of a quarter and is located under the DIMM cover. Removing it my clear what you've messed up but I doubt it as using the initialize feature should have restored things to stock. I'll see if I can get a decent pic of my CMOS dump tomorrow.
