Hi Yhlu,
Thanks for your response.
I was mainly looking at Geode LX based processor boards and associated chipsets. I dont think that ASL/AML for these boards is available. But my question was generic, i mean what if I plan to use Linux BIOS for a custom board and I want to comply with ACPI. In that case how do I get the necessary ACPI tables in ASL/AML. Because ACPI compliance is compulsory for my work. Otheriwise I might have to get the required files from gerated by one of the comercial BIOS vendors.
Let me know what you think about this.

which MB or chipset?

for MCP55, you may need to modify DSDT in seregenti_cheetah/8132/8111.
you may need access to nvidia mcp55 NDA doc.

you may not look at your MB current DSDT in Normal BIOS. that dsdt is
belonging to IBV ( Phoenix or AMI) instead of MB vendor.
