Holding out on me, eh? ^.^

A bios update will "usually" allow a motherboard to accept all speeds of xeons. Afaik there isn't much you can do if the latest bios does not work.

With the MS-6135 there are VER1 and VER2 boards and I have a VER1 board with BIOS 62710 07/15/97 A6135MS V1.4 01/28/99 which AFAIK is the latest. The system currently has 2 x Intel Pentium II Xeon (Drake) 450MHz @ SL33U 1MB L2 cache 2.0 volt CPUs.

I just found 2 x Intel Pentium III Xeon (Cascades) 700MHz @ SL49P 2.8 volt 1MB L2 cache CPUs and am wondering if there is any chance I can get them to work in my MS-6135 VER1. I tried plugging them in, but the system failed to post.

I just spotted that the version and date information reported by the SMBIOS is rather strange so did some checking and basically it's incorrect.

I adjusted SIV to compensate for this and as from SIV V5.49 Beta-07 it reports the same BIOS version and date as is displayed when the system posts for my VER1 board.

If you have an MS-6135 VER2 board please will you check what get's reported in case I need to further adjust SIV?

I also tried the 2 x Intel Pentium III Xeon again and my post card is reporting 2A FF. Looking at http://www.bioscentral.com/postcodes/amibios.htm then the 2A may be 8742 keyboard tested, but does not mention FF

The last time I tried it was nearly 20 years ago, but I would start with checking, whether the BIOS has the required microcode for your CPU. If not, you should add it and flash the board with such modded bios. I think I've use cbrom to do it, this looks like a guide: http://mrufer.ch/pc/tualatin4_e.html

Thank you for the suggestion, but I don't think it's getting as far as loading the CPU µCode and I know my Compaq W8000 does not have the µCode for it's Intel Xeon MP (Gallatin) 2.70GHz [C0] SL79Z CPUs (it whinges saying this) and still posts OK so don't think this will help.

Looking further the Intel (Cascades) [B0] revision 1 µCode is dated 2000-06-16 so there is no way the 01/28/99 BIOS can have it.

I just checked and Windows 2003 has the Xeon (Cascades) µCode so should load it even if the BIOS does not.

Hi. I just bought two 1ghz Pentium III Xeon Slot 2 CPU's. Now I need a motherboard that can handle them. I did some googling, but wasn't able to find a clear list of motherboards that support these CPU's. Can someone give me a list of motherboards that will work? Thanks.

Not much of list but this could be a fun one.

I have one of those, thanks to red-ray. I just recently got 16gb of ram and 4x 900mhz cpu's for it. I'm just looking for a case for it.

Man that board is a thing of beauty. I have two dual slot 1 supermicro motherboards. Bob have you tried using the system yet?

I have a 900MHz 2MB Slot2 Xeon, just got one from somekind of large IBM server awhileago. Allways wondered, can it be used for something without paying an arm and a leg, but reading this, it is better just hold on to it or try to sell it.

VERY yummy! 😜

Are there 6 VRMs?

It sure looks like there are six of them. That board fully maxed out cpu and ran wise would make a seriously awesome windows 2000 server system

AFAIK W2K Advanced Server is limited to 8GB and to support 16GB you would need Datacentre Sever which was not included with MSDN.

I expect 2003 Enterprise Server would be a far better option as it supports 32GB and is in general much better than 2000.

I did recently give it a smoke test, when I got the ram from ebay.

Yes you are absolutely right I forgot about ram limitations of 2000. 2003 would work better

Excellent! That is just super sexy looking. I hope you can find a suitable case for it.

I have Dell Precision 620 board with PSU and accessories (pretty much everything except the case), I am planning to get the board to run 2MB CPU's on 133 MHz bus (with lower multiplier). On Dell you set the CPU speed with floppy disk (utrility called sprfrq2.exe). It basically sets multiplier and the resulted speed cannot exceed rated CPU speed, otherwise the board wont' boot iirc. I had a complete 933 MHz Precision 620 once and experimented with it, though did not have 100 Mhz CPU's to test. But it had CPU speed option in BIOS ("Compatibility") which seems to be 100 MHz speed setting and on the board there is unsoldered jumper stating "100 Mhz" so it is possible that it works.
Though not sure I can get it to work at 133 Mhz FSB. I can live with 700 or 900 MHz CPU but I want it to work at 133 MHz bus speed 😀 100 MHz seems such a waste for that reat CPU.

Hi! I also have a Precision 620 currently running 2 x 1Ghz 256K 133Mhz Xeons. Would 2 x 900Mhz 2MB work with it? I would like to see how they perform vs the 2 x 1Ghz that i have and don't want to buy them if they don't work since they can get quite expensive...
Thanks!

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.
