Re: [coreboot] sgabios no console output from Seabios (was: coreboot Digest, Vol 113, Issue 17)

[WANG FEI]

Wang Wen,

I found following message in the coreboot-seabios log,

[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.3.4-5.fc17.x86_64
root=UUID=c4d4a429-d880-4caa-831e-9e95b5595f67 ro rd.md=0 rd.lvm=0 rd.dm=0
SYSFONT=True KEYTABLE=us rd.luks=0 LANG=en_US.UTF-8 console=ttyS1,115200n8

It shows "console=ttyS1,115200n8", it means the Linux kernel is using ttyS1
as the primary serial console, which is I/O port 0x2f8. But the seabios
configure file shows seabios is configured using I/O port 0x3f8. it might
be the problem.

Please run "make menuconfig" in seabios and reconfigure the serial port to
0x2f8, let us know any difference.
