Ive had an on going problem with my Motherboard for about a year now where it will not save settings even though i have changed the battery many times and cleared RTC settings
So i thought id try a new Bios chip , all went well installing and the chip is sat in the socket fine and the correct way around , i cleared RTC and put a new battery in but now i get nothing ? just spinning fans and power but system will not boot - Just gives me a black screen ?
From your description I take it that you used a PROM programmer to program the flash PROM on your motherboard or did you buy a new PROM? (from where?) If you have fitted the chip in the socket yourself you can put it in at a slight angle so that it does not make proper contact. remove the chip and refit the chip making sure that it's down flat I have made this error many times myself. If the computer will still not boot, then the provided that you have cleared the CMOS memory it means that you have programmed or got a PROM with the wrong data in it.
I see, you did tell them when you purchased the chip what motherboard it was for? I would return it and get them to reprogram it, providing the motherboard works when you put the original BIOS chip back in. I was surprised to see in the illustration that it was a DIL type chip, the common mistake putting this type in is to bend one of the legs of the chip under the package. I have done this more than once.
Right had another look this morning (in the daylight) and there was a tiny clear piece of plastic wedged in the ram slot ? How that got there ill never know but i hooked it out with a small screwdriver and now is all working perfectly
