First post, by Odiseo
I am the same person who opened this topic and this one.
The original RTC and the one I bought from someone in China had a flat battery. I don't know how to solder, so I bought another RTC. Again on eBay, but from someone in the UK instead of China. The auction had a picture of an RTC labeled "DS12887+" (the one I thought I needed), but the one I received is labeled "DS12887A". Is there a difference between the two?
I put the RTC into the socket and the error message "CMOS Battery low" was no longer displayed after POSTing. The system does display the following error message: "CMOS Battery failed / defaults loaded". I updated the date and time in the BIOS and both are still correct after rebooting or shutdown.
In contrast to what was the case when the previous RTC was still on the motherboard, the system can boot from a floppy disk now. That allowed me to run the installation program for Windows 2000 from CD. The installation finished and appeared to have been successful, but after rebooting and passing the POST (which detected the hard drive), the system (or Windows?) said it couldn't find a hard drive. How can this happen, bearing in mind that the system just installed an operating system to that same hard drive?
I figured that maybe I had to put a jumper on the hard drive's Master pins. After I had done so, the POST still detected the hard drive, but the following error was displayed: "Hard Disk Fail (80)". I also put the jumper on the Slave pins and, later, on the Cable Select pins, but in both instances the POST didn't even detect the hard drive.
I wanted to update the BIOS but I can't find any suitable BIOS images. When the system POSTs the following model number is displayed: "2A59CC3AC". This number is also displayed when I start up the Award flash utility from DOS. The chipset is Intel 430FX.
Below is a recap of my questions.
- Is there a difference between DS12887A and DS12887+?
- How can I fix the CMOS error that reads "CMOS Battery failed / defaults loaded"?
- How can I get Windows 2000 to detect the hard drive it is installed on?
- Where can I find newer BIOS images for this motherboard? The archive file that can be downloaded on this page contains an image for model number 2A59CC3B. But I have model number 2A59CC3A.
