Returning to the MB Slot1 BXCEL PCChips M726, I have interesting news, I started by checking the contacts of the CPU, which I had previously cleaned, then I change CPU and switch from Celeron 333 to a PII 400, with the other CPU the VCORE goes up a little about 1.9V, a little low but still better than almost 1.7V, after other useless boot attempts, I try to tilt the CPU a little, to see if something changes, in fact a couple of codes appear, I think 43 and 42, I didn't take a picture, but it made me understand that the problem is of contact with The slots of the Slot1, so I pull out the CPU and start cleaning the pins of the Slot1, I removed a surface layer of blackish oxide, then I try to spray the IPA, I put everything back on and try again, it doesn't go!
I check the voltage of the VCORE, it has risen beyond 2.20V, a little high but acceptable, and then as we will see, maybe the tester is slightly above the real value .
I put the Celeron back, and after a couple of attempts, I see the post codes starting to scroll, a sign that the PC starts up, in fact shortly after there is a double beep and a screen on the screen !!!
I check the VCORE on the Mosfet, it is always above 2.2V, but from the BIOS the indicated value is just above 2.0V, a sign that maybe there is some component that brings the voltage to standard values.
However, for the moment I am more than satisfied with the result, now I just have to connect the usual IDE CF adapter with memory card, and from DOS do some benches and diagnostics, I do not expect results of a certain level, indeed the opposite, but who knows, from what I know is that the ALi chipset, does not shine for speed, but it is quite good in reliability.
