[coreboot] Coreboot on Tyan S2892

Hello, I'm the newb that Myles was kind enough to address in the
original post.

Sorry in advance if I ask stupid questions that are covered in a FAQ or
the like.
If that's the case, I can't seem to find it, so feel free to point me in
that direction.

What I'm trying to do, is take an existing Linux installation (on a SATA
disk) and
shrink the BIOS-related part of the boot time.  I don't ever need to
boot with different
kernels or ramdisks.  They will always be located at
/dev/sda1/boot/<static kernel|initrd name>.

So I grabbed the latest buildrom from SVN, and had trouble doing a 'make
menuconfig' on various
Linux boxes.  I was finally able to do a 'make menuconfig' after
installing ncurses on an Ubuntu box,
and then after selecting the appropriate options for the Tyan S2892, and
FILO (before I saw Myle's response),
the long awaited tyan-s2892.rom file appeared in my deploy directory.

In the discussion between Myles and Marc about SATA/FILO, I became more
confused about what my payload
should be.  Based on my system configuration, should I use FILO?  LAB?
GRUB2?  What is "legacy mode" SATA?

The first ROM image I created painted some nice pinstripes on the
display after a warm reboot, and when I
fully powered down and started again, I got a nice alternating tone from
the PC speaker.  I'm suspecting this
has something to do with my payload.  Either it is wrong entirely, or it
needs additional configuration.

Serial console output seems to indicate that basic coreboot
initialization was happening, but maybe never
got to the point where it could give me useful VGA output.

Sorry also for top-posting, but I'm stuck with Outlook.

No problem.  I should have been clearer in the original response.  You
probably helped clarify it for everyone else.
