OK, assuming you have a 256KB ROM chip and your VGA BIOS is 64KB.
I have 256KB ROM and I got some VGA BIOS. One of them is exactly 64KB but that one out of script is smaller (see below).

Why?

Not sure about this. I'd rather not change it unless really necessary (it isn't in this case, I think).

This is wrong.
ROM_IMAGE_SIZE is the maximum size the coreboot code can use (without payload, without VGA ROM, etc).
Something like 64*1024 is usually ok.
OK, I will look at that. I got these options out of Config.vga.filo.

Never used $(HOME) here, but I assume it works? If not, try /tmp/filo.elf and copy your payload there.
I don't think I got problems with this but I can try an absolute path.

In an earlier version I changed Config.lb in src dir to get VGA BIOS. But now it isn't included. If it is important, I could post it later.
Plese post it.
On monday I'll send it to mailinglist.
But the above patch comes from an 'svn diff' at the top-level directory, correct? I.e. all your current changes are in there?
Yes, these are actual all changes on top-level dir of corebott sandbox.
Also, where did you get your VGA ROM from? Using which tools
(awardeco,
amideco, phnxdeco, other)? How big is it exactly?
On http://www.coreboot.org/VGA_support at bottom there is a perl script. Using this I got my VGABIOS. This is 60416 bytes big
OK. Which vendor BIOS does the board have? Can you use awardeco/amideco/phnxdeco to get the VGA BIOS and compare it with the one from the script? Just to be sure that worked fine...
I'll try this on monday. I don't know, what vendor BIOS was in ROM. I used the original BIOS got from VIA.
(optionsrom is 57344 bytes which I used at last).
Huh, what's that? Where from?
Look at post of Stefan Reinauer (http://www.coreboot.org/pipermail/coreboot/2008-March/031664.html)
filo.small.elf is 27312 bytes big. So don't wonder what number this is.
Are you sure this is ok? The smallest usable FILO I've used so far is ca. 57 KB. Your 27 KB FILO looks _very_ small.
Also, please use the latest version from
% svn co svn://coreboot.org/filo/trunk/filo-0.5
Type 'make' (that will generate a Config file), then edit Config, then type make again.
Uwe.

I'm not sure if payload is ok. But at first I used a bigger one and the errors where same. So I removed all I think I'll not need. How can I test payload?
But if your smallest payload is 57KB and I will use normal and fallback and a VGA BIOS I get space problems. About 64KB for VGA and 2 payloads about 57KB are 178KB. Is 78KB for normal and fallback not too small?
I will update my filo and look at that config. Maybe there is some special on my config (e.g. I only need ext2, so all other are deactivated).
