My research taught me that most older 486 motherboards have a similar CMOS substitution chip that you can purchase, or modify the one you have with a battery as shown.

the F1 bios menu thing did not work no matter what options I chose. The fix is to do the mod to the CMOS chip, or gamble on a substitute replacement.

I'm glad it was successful. According to them, the cmos setting was preserved. If the battery is completely discharged, it must be restored to the original state. The setup menu should work, but then there was no need for it.

You have to enter the setup utility.Power off the machine,connect AT keyboard to the rear port, power on,press f1, load the bios setup defaults, enter the hdd parameters,in the first menu (Standard CMOS setup) (Cylinder,Head,Sector,Wprecomp) save the

thank you so much for the info, wished I would have known previously, however I found the motherboard manual online, and located the Dallas CMOS chip soldered to the board. Found a lot of youtube fixes online. Dremel tool and some soldering, added an

I'd say it's much easier to do the external batter mod than replace the whole Dallas module. I've done it, works fine. There is a chip in the socket next to the module, best to remove it and put back when you finish with the mod.

Contact George Castonguay at PPM. He is a Jedi when it comes to these machines. In fact, since you just got it, a good investment would be to have George come in and go through the machine and get it calibrated. 603-895-5112 They also sell parts

I have a silver aluminum z axis sensor that is not mounted, I need to know where it goes. The sensor has a picany rail type mount, triangular rail insert type. It is located in the board support nest area. Seems like it might go on the inside of the

Hi, Someone can tell me what the difference in UP2000 and AP-25? What is the best machine? Thanks

I have an ap-25 and wish i had gotten the UP-2000 instead. How's that for an answer? The main difference is that the ap-25 uses linear motors and air bearings, whereas the up-2000 uses ball screws. The linear motors are faster, but the whole thing i
