1) Include llshell.inc in your northbridge Config file
2) In raminit.inc (or whatever), make a jmp out to low_level_shell, setting
a return label in %esp.
For example:
ram_set_registers:
mov $llshell_ret1,%esp
jmp low_level_shell
llshell_ret1:
/* Disable and invalidate the cache */
invd
mov %cr0, %eax
....
3) Optionally, comment out two lines in ramtest.inc:
5:
CONSOLE_INFO_TX_STRING($rt_toomany)
// post_code(0xf1)
// jmp .Lhlt
otherwise, a ramtest failure will hang
4) build and flash as normal
If it worked, the speaker will beep, and you'll get a shell.
Type help or ? at the prompt for a list of commands.
