[coreboot] [PATCH] Asus M2A-VM
Carl-Daniel Hailfinger
c-d.hailfinger.devel.2006 at gmx.net
Mon Apr 6 01:05:27 CEST 2009
This is the state of my v2 tree with Asus M2A-VM support. The patch is
against the AMD DBM690T, so you have to compile the amd/dbm690t target
for your Asus M2A-VM.
Notes:
- If you want a working NIC, revert the part enabling MMCONFIG in
LinuxBIOSv2-asus_m2a-vm/src/boot/hardwaremain.c.
- If you want a working NIC and ACPI support for SATA, go to
LinuxBIOSv2-asus_m2a-vm/src/mainboard/amd/dbm690t/acpi/dsdt.asl and
enable the SB5 EVIL HACK and comment out the active
"OperationRegion(SB5..." instead.
- Thermal setup is wrong.
- More than 2 GB RAM will not work (SATA will hang).
- FILO will usually work. Sometimes, you may have to poke the reset
button first.
Suggestions:
- Revert the MMCONFIG stuff. Ignore ACPI for SATA.
