Well, here are the problems I had to go through to get my 8RDA+ to work.
1. During boot, it kept telling me that "BIOS has been flashed or JCLK has been changed. Please make changes in CMOS and save!", although it was the first time booting after making initial CPU clock changes in CMOS. After that, it kept going in that loop, keeping me from booting. I fixed it by flashing the bios to the most recent.
2. The flashing to BIOS kept my system from POSTing, giving me a POST code C1, which indicates something wrong with the memory. The RAM works fine on my other system, and passes memtest. I fixed this, but reseating the CPU (dunno why that fixed it).
Then it gave me the same problem as #1, but messing with jumpers the way instructions tell me that I shouldn't have to, it got fixed.
3. Next, I found that the mobo would give me a "BOOT FAILURE" error message when hooked up with my Sony CD-ROM drive. I was in a situation, since I wanted to install Win XP, but couldn't unless I was able to use the CD-ROM drive along with the HDD. Fixed it by using my CR-RW. 8RDA+ must have incompatibilities with the Sony.
4. Then, even when I set up in BIOS to boot to CDROM only, it just would not boot to CD-ROM. I got around this by using the Win XP startup disks provided by Microsoft.
5. When installing Windows XP, it gave me a long error message/blue screen about the BIOS not being ACPI compliant. I got around it by disabling ACPI during install process.
6. Once in Win XP, my mouse and/or keyboard would not respond after bootup. I fixed this by unplugging the Power LED connector on mobo, as suggested by 8rdafaq.com. It seems to fix it.
7. Now, I am running Win XP, and am installing my common programs to see how stable it will run. It seems like it's working fine, except that none of the case LEDs are lighting up. This seems to be a common problem for many 8rda owners. I can live with that, so that's fine.
8RDA+ was the first board that gave me so much trouble that I considered giving up. And I've been building computers on my own for over 10 years now 😛 Hats off to 8RDA? hehe
