you need


Snow leopard installation disc 10.6.3

Tonymacx86 [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] Supported + [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] 2.1.1 works

some older video card that will install thxe osx ( then you can change it and play with video kext ) i used evga 9800gt

if you use some newer card like nvidia 470 gtx it will just freeze while booting


config i tested it on


- Supermicro X8DAi

- 2x 3.33 Xeon X5680

- 12 GIG Memory

- Evga GTX 285 ( first install with Nvidia 9800GT or other older supported video card ) you can get GTX285 working but you have to update to 10.6.4

- OCZ Vertex SSD


all working great

Glad you are done with this mobo.

I think that you've ancountered a problem with Chameleon 2.0 RC4 r684 due to boot file.

Will try vanilla installation using my usual order - bootflash with Vanilla SL installation image + Cham 2 RC4 + PCEFI10.5 + FakeSMCv2.5. Cham2's original boot often causes KPs or not-booting.


Can you tell about Speedsteps, Sleep on this mobo and so on?

sleep does not work


speedstep i cant check i dont know what program to use that shows speedstep working

but when i had in smbios id MacPro4,1 or 5,1 i had OpenGL very small scores

after i upgraded chameleon rc4 to rc5 i got the full speed ( opengl is in thousands instead hundreds ).

also rc5 is supposed to fix the speedstep issue and sleep ( not for me )


if you can supply me with speedstep diagnostic soft i will confirm it

Where did this take you?


I am planning / dreaming / gathering info on building a dual Xeon hack pro with a Supermicro X8-something motherboard.


It is not worth it if I can't be sure there is functioning ECC, and speedstep is much appreciated. Sleep I can also do without.


But if the point is to get as close as possible to a real Tylersburg Mac Pro, I'd expect most if not all things to simply work.
