Further to this reply, Appendix C (POST Code Diagnostic LED Decoder) seems to be incomplete. Here is a list of additional BIOS codes which can be translated:
Your diagnostic code LED color pattern:
<R G R 0>
translates into these nibbles:
1 0 | 0 1 | 1 0 | 00
put the upper and lower nibbles together and you get A4h
Look at the link for A4h and you'll find description ACPI_LOAD_RSDT.
I had the same problem for S5000PAL
