Hi,
I have an old computer for work which broke and I am trying to get it set back up. I have replaced RAM, motherboard, and CMOS battery (old Dallas DS12887) and I finally get it to POST.
What's interesting is that when I insert the new replacement DS12887+ into the socket that I soldered onto the board, I no longer get the errors "CMOS Battery Failed", "Memory Size Decreased", "CMOS Time & Date Not Set", but I cannot hit F1 to enter the BIOS setup. If I plug in the old failed DS12887, I get the error messages that I listed above, but I am able to enter the BIOS settings.
The original problem that I ran into is that when I plug a Seagate IDE HDD into the board, the CPU doesn't POST. My thought was to try to replace the CMOS battery, configure the boot sequence in BIOS, save the configuration and this would allow me to use the HDD and boot from it on startup. Since I am using a new motherboard, it's a reasonable assumption that the BIOS may need to be configured. It appears that since the CMOS errors are gone, the Dallas RTC chip that I used to replace is fine, but I am curious as to why I can't get into the BIOS to configure the HDD.
I'm not sure whether to focus on the CMOS battery or the HDD. I'm running out of things to try. UGHHHH! Any and all questions and suggestions are welcome.
By the way, the motherboard I am using I believe is a Socket 5 Intel Premiere/PCI II (PLATO, I think). BIOS is AMIBIOS American Megatrends, Inc. Version 1.00.12.AX1.
The only reason I want to fix it is because all of the integrated boards that plug into the motherboard are ISA boards and they do various functions on a piece of equipment in our R&D lab. They are all custom boards and there's no easy replacements. I want to get this CPU up and running, while we work on delivering a suitable modern day replacement, which is both expensive and more importantly time consuming.
Thanks!
