Notes

  • The ASUS F2A85-M CSM is same as F2A85-M.
  • get VGA from original bios using this:

Source: http://www.coreboot.org/pipermail/coreboot/2012-December/073133.html

for internal VGA: Boot the legacy BIOS, and use VGA_support chapter

extracting from your system: dd if=/dev/mem of=vgabios.bin bs=1k count=64 skip=768

  • Add VGA bios in the menuconfig
  • If you use PS/2 de-select legacy free
  • De-select running option ROMs, Seabios will run the ROMs that coreboot loads into memory so you should get a text display from Seabios
  • It is required that seabios is the coreboot payload for the F2A85-M or the internal VGA will not be initialized. But read SeaBIOS for how to add payloads to SeaBIOS and set SeaBIOS' boot order to run your payload.
  • Hotswapping the PDIP BIOS chip has some issues (most likely USB3 XHCI, disable it in original bios before hot-flashing to coreboot). Drop a mail to mailing list if you have issues.

TODOs

  • test virtualization
  • test HDMI
  • update VERB tables
  • test suspend

Hardware info

This board ships with a socketed Winbond 25Q64F, 64 Mbit (8 Mbyte) chip, in PDIP 300 mil package:

Winbond 25Q64F

The chip manual is available here

For out of band flashing, I use a

 3M test clip model 923739-08-ND

It has .300" spacing, 8 pin DIP clip, gold finish and 'headless heads'. I hook this up to a bus pirate. This works but reading and writing take forever:

# time /usr/src/flashrom/flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w 20130826-coreboot.rom
flashrom v0.9.6.1-r1669 on Linux 3.8-2-amd64 (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25Q64" (8192 kB, SPI) on buspirate_spi.
Reading old flash chip contents... done.
Erasing and writing flash chip... Erase/write done.
Verifying flash... VERIFIED.

Memory

I use:

2x 2GB DDR3 modules in blue slots:

#modprobe i2c-piix4
#modprobe eeprom
#decode-dimms
