Hello!
Just got a Supermicro S2DGE mobo. Testing it with one SL49P Xeon 700/1M Cascades CPU (2x SL49R 700/2V are on the way) and got an issue.
Everything fine, except microcode error and wrong frequency show on BIOS summary screen (550 MHz), but actually CPU is working at 700 MHz.
I assume it is BIOS issue, but:
1) I have 2241/Rev 1.6 bios, that is latest available to download
2) Mobo officially support Cascadi CPUs
3) There is a mention about rev 3.1 bios on supermicro's FAQ - https://www.supermicro.com/support/faqs/faq.cfm?faq=2192
So does anyone had this issue and successfully fixed it?
I have very little info on how to edit BIOS files, but there is a program called MC EXTRACTOR which pulls out CPUID's from a BIOS rom file. I used that on your 2241 BIOS file and got only 6A0 as the last CPUID microcoded in. SL49P is 6A1, as per https://www.cpu-world.com/CPUs/Pentium- ... 001M).html
6A0 (SL3U4, SL4GD)
6A1 (SL49P, SL4RZ)
6A4 (QZ85, SL4XU, SL5D4)
I'm sure there is a way to add in the 6A1, but I have very little experience other than requesting it at bios-mods.com.
However, I did find a s2dg2b30.rom file (rar'd, attached) that is a BETA for the S2DG2 motherboard, which looks like it accepts the same BIOS as your S2DGE board, but triple check that before continuing. This DOES contains the 6A1 microcode.
