Re: [SeaBIOS] Does SeaBIOS support eMMC?

[Alexander Couzens]

Hi Mario,

SeaBIOS supports eMMC, but it's a bit hacky.
For eMMC in ACPI mode you have to add files containing the address
of the eMMC to the cbfs.
No idea, if eMMC in PCI mode works out-of-box.

cbfstool coreboot.rom add -n etc/sdcard0 -f /tmp/sdcard0 -t raw
cbfstool coreboot.rom add -n etc/sdcard1 -f /tmp/sdcard1 -t raw

Best,
lynxis

PS. Tested on a baytrail based chromebook.
