Kernel panic with installation DVD

[citizenofnowhere]

Would like to say in advance that I appreciate any help, and have gone through the forums but can't seem to find anything like the problem I have here.

 

I have here a custom built PC with the following specs (I've gone through the HCL, it looks like it's compatible, but I could be wrong)

 

AMD Sempron 2600+ processor

Abit nf-7 motherboard

ATI Radeon 9550 graphics (thought it is recognized for some reason as 9600 on all my systems, and the installation only recognizes 16MB of ram though it's supposed to have 128MB)

Western Digital 80 gig IDE harddisks

SONY DVD-RW DRU-700A

 

When I pop-in the installation DVD (Jas 10.4.6) and boot up after a short pause I get a message saying "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button".

 

The gist of the verbose output is that it identifies my processor correctly, but says it doesn't have SSE2 or SSE3 support. I was under the impression that semprons do have SSE2 - could I be wrong?

 

under AppleACPICPU it says Enabled

 

The very next lines are:

 

panic(cpu 0 caller 0x0019CFFC): commpage no match on last routine
Debuger called: <panic>
Backtrace, Format - Frame : Return Address (4 potential args on stack)

 

Then there's a bunch of hex numbers, ending with:

 

Backtrace terminated-invalid frame pointer 0x0
Kernel version: Darwin Kernel Version 8.4.1........; root:xnu-792.7.90.obj~1/RELEASE_I386

 

Then it just stops.

 

Have tried the following boot options in various combinations: -x, -s, platform=ACPI, platform=X86PC

 

Is there any hope?

 

Thanks again!!

ABIT NF-7 is a SOCKET A motherboard. No Socket A CPU has SSE2. Therefore, there's no such thing as a socket A Sempron with SSE2.

 

You'll have to upgrade your computer to something which supports a SSE3 enabled CPU, so you'll also be able to use the latest 8.8.1 (10.4.8) kernel.

Choosing an Intel CPU is the right choice, because mainboards which have Intel chipsets seem to have the best compatibility.

 

Even a Celeron D (check that it has SSE3, in some shops you can still find old Celeron Ds which have only SSE2) is enough.

Thanks so much for the quick response!! I guess this settles it.
