Thanks for your great help.
My mainboard is cougarcanyon2 ,now I can boot
to DOS by the solution of Coreboot+Seabios.
But it can't install OS(both Win7 32bit , ubuntu
32bit,android) by CD-ROM.
1.I use CD-ROM
to install the OS ,but it seems that both android & linux & win7 will
halt during the installation .
2.Firstly, I install the
OS(android , linux , win7) into sata by traditional UEFI bios.
Secondly, I flash the coreboot.rom on my board.
I can boot to the OS (android , linux) which is installed by traditional
Generally speaking,does coreboot support to
use CD-ROM to install the OS?
