Phenom on T180

Hello, and thanks for your good job.

I have tried the bios Acer Aspire T180 With OC 1234s282 and it runs good with the MCP61M-AM mother board equipped with a 5000+ Brisbane. I uses 226 MHz FSB with Super Talent Dram 800MHz running at 840MHz. (2x1GB but all other rams I have tried fail the POST ram test).
What is the difference with the ABIT bios?
Is it possible to use a 4 core processor like Phenom?
I have searched in this forum, and response is not so clear.

Thanks.
