similar to: Gfxboot COMBOOT module vs Ubuntu patches

Hello all, i announce you the gfxboot COMBOOT module which is written in assembler. Since i didn't find as much spare time as i have hoped last weekend it is far from complete. Nevertheless the module is able to interact with the bincode ([1] and [2]) in the bootlogo cpio archive from the openSUSE 10.2 mini cd. So far it is able to call the bincode gfxboot code and setup some menu entries.

So here it is. Ugly and far from acceptable shape but nonetheless it seems to work. Parts are borrowed from syslinux core and of course the gfxboot patch for syslinux 3.63.

Hello all! I saw on ubuntu that when syslinux starts, it starts a pop-up with language selecting. I think (?) (not sure) this is from a patch of syslinux named gfxboot. And I want to make a bootable cd and I need to know how to obtain that with syslinux, or how to patch it with gfxboot! Thanks all! ----------------------------------- Shadow

Ok, here is the first try to turn the gfxboot wrapper into a com32 module. I had to extend the interface to the gfxboot core a bit to get it working. So it works only with latest gfxboot from git://gitorious.org/gfxboot/gfxboot.git Steffen -------------- next part -------------- A non-text attachment was scrubbed...

This is the latest version of the gfxboot module. It's supposed to work on all Syslinux derivatives. I am not sure about the copyright notice and would appreciate any input. - Sebastian Index: syslinux-3.74-pre17-2-g2a9ddec/modules/Makefile =================================================================== --- syslinux-3.74-pre17-2-g2a9ddec.orig/modules/Makefile +++

Hey Steffen, What are your plans regarding the COMBOOT module for GFXBOOT ? Do you plan a merge into syslinux main code or maintain it as a patch ? Regards,

If the file size wasn't a multiple of 64KB, we could overwrite the next entry in the malloc arena so reading the initramfs would fail.

gfxboot uses those three calls, but currently doesn't really handle returns from them. syslinux_boot_linux (lib/syslinux/load_linux.c) can return ("bail" label). syslinux_local_boot (lib/syslinux/localboot.c) has a comment which says "returns only on failure". The documentation for "Local boot" in doc/comboot.txt says "Does not return". Which is correct?

Hello, I think I found another problem with gfxboot, and I think it is completely unrelated to the 'packed archive' issue. Again I tried using gfxboot with the Ubuntu gfxboot archive, this time with EFI64, using a real EFI-capable machine. I first verified that everything else actually works by commenting out 'ui gfxboot bootlogo' and got a working menu. Uncommented the line

Ubuntu CDs use multiple configuration files and the include directive as well as gfxboot, so it's useful for gfxboot to support these.

The COM API provides a function to read from disk (int 22h, AX=07h) which needs a destination buffer aligned on a 512 byte boundary. gfxboot uses this function but doesn't ensure its data buffer is properly aligned. This leads to failures on a few machines (HP Pavillion dv5): gfxboot: isolinux: Disk error 09, AX = 424F, drive FE https://qa.mandriva.com/show_bug.cgi?id=48814 has a bit more
