Intel G7ETA Server Mobo

Hi this is my first post,

I'm doing my first retro PC build and I'm looking to get a manual for an Intel G7ETA mobo. It'll be part of my first retro PC build, along with two Pentium III Xeon's (1000mhz 256kb SL4HF). Ideally it would be great to get a manual for the board but I haven't been able to find one. If anybody could could give me any info on it, ram info, etc. would be really appreciated :D

Also will it even support the 5/12V core voltage for the Xeons I have?

Hi Sean!

These forums are a little quiet these days ...

It looks like you might be out of luck getting the necessary manual for the G7ETA motherboard, unless you try Intel directly. Their online support is quite limited for much older server boards it seems. There is a Youtube video in Spanish showing off the board and the case sticker which has some of the settings, not sure if that's of use.

From the looks of the board, you might need a specific PSU, so if you don't have compatible server equipment it may not run properly. My dual Athlon MP build needed an ATX PSU with a separate 5V connector, which was not available on every desktop PSU.

A posting on the Computer Shopper forums suggests that the board needs ECC SDRAM, and the maximum supported would be 2GB i.e. 4x512MB ... 732&page=2

Also, do you know what chipset the board comes with? Wikipedia only lists the 440GX, 440BX and 450NX as supporting dual Xeons ... I_chipsets

According to that Computer Shopper link above, the guy bought it with a couple of P3 1GHz Xeons - it's not clear if it could run them properly as older chipsets didn't officially support 133Mhz Front Side Bus, so if it runs the CPUs at 100MHz FSB then you'd have a pair of 750MHz CPUs (7.5x100, instead of 7.5x133).

Overall it would be cool to have a Dual PIII Xeon 1GHz setup, but the use case even for retro might be limited, unless you are planning on running a server or basic desktop. It doesn't have AGP, so gaming options would be quite limited - maybe a PCI Voodoo 5 or something slightly newer. Do you have any other old gear, or is the only board and setup you have your heart set on?

Also, you could try over on - there are a couple of retro dual CPU fans who might just have more information for you.

Okay so I got everything working a while back, I thought I'd post some info here.

Firstly the cpus work perfectly with the board, full speed. 550mhz Xeons may not work due to fsb, but I have one so I can test it if somebody wants to know.

The motherboard MUST use a server power supply. There is a I2C connector on the board. IT IS NOT 12V EPS!!!

The power supply consists of an enclosure and up to two power supply modules.
Enclosure part no. Delta Electronics RPS-350 B
Power Supply module part no. DPS-360AB

Oh yeah this might help too :)

I have a Radeon 7000 installed at the minute as it has DVI out. As the board has PCI-X (not express) I can get high end server nics, raid controllers, etc. The only main drawback is that the board does not have an AGP slot.

If anybody needs any more info let me know :)
