Re: multiboot on EFI

Re: [PATCH] New frame buffer detection algorithm and loadrom command for efi platform
Hi,
svn rev 2043 patched loadrom.diff on imac81 with ati fglrx.
I find loadrom needs time when called in menuentry, otherwise linux load
fails or loadrom fails. So I had to use sleep.
Then it works very nicely.
--
insmod sleep
menuentry loadrom hd0,4 sda4 {
search --set /ivt.bin
loadrom /bios.bin /ivt.bin
sleep 1
root=hd0,4
linux /vmlinuz root=/dev/sda4 video=vesafb
initrd /initrd.img
}
This is not apparent from command line with manual entry pauses.

Hi,
This patch improves the frame buffer detection algorithm. It uses pci
to find the video memory base, then scan it for frame buffer.
It also add a loadrom command which can be used to enable accel
graphic driver. The idea is that you can grab the video bios dump, and
optionally the IVT from pc mode, then load them in efi.
To grab bios dump:
sudo dd if=/dev/mem of=bios.bin bs=65536 skip=12 count=1
You can also include the system bios by changing the count to 4.
To grab IVT dump:
sudo dd if=/dev/mem of=ivt.bin bs=1024 count=1
Then, to load them in grub-efi (ivt.bin is optionally):
loadrom /bios.bin /ivt.bin
Here are some of the findings concerning different video cards:
Old 32-bit efi model, intel card:
Works with intel driver, no need to load vbios or ivt.
New 64-bit efi model, intel card:
Works with intel driver, needs to load vbios.
New 64-bit efi model, nvidia card:
Works with nvidia driver, no needs to load vbios or ivt. However, the
backlight value is set too low so desktop is barely visible. You need
to use a small tool to adjust backlight. The nv driver doesn't work.
New 64-bit efi model, ati radeon card:
Works with fglrx driver, needs to load vbios and ivt. The radeonhd
driver doesn't work.

unknown command 'boot' with coreboot/grub2
I've built grub2 from source (r2045). My modules list is:
MODULES=minicmd normal ls cat help ext2 iso9660 reiserfs xfs fat pc gpt ata
serial memdisk multiboot linux configfile search tar
but when booting a multiboot xen kernel I get
unknown command 'boot'
My grub stanza is:
menuentry Xen 3.1.4 {
set root=(ata0,1)
multiboot /boot/xen-3.gz no-real-mode com1=115200,8n1 console=com1,vga

module /boot/initrd.img-2.6.18.8-xen
}
Am I missing a module, or is the order wrong?
Thanks,

Support for precision formatting in grub_printf
* kern/misc.c: modified grub_vsprintf to parse and handle
precision formatting
Thanks.
Unfortunately, the patch can no longer be applied to current svn without
a conflict.
The precision parsing and '%s' precision (truncation) handling is
already implemented.
But the '%d' precision (zero fill) handling part of your patch is still
missing in the code.
Could you please repost an updated patch in diff -u format?
Note that the current code does not use a format2_default flag buts sets
format2 to ~0U ('infinite' :-) if no precision is specified.
Thanks

Overlaying default grub.cfg makes qemu fat: partition inaccessible
Hi all,
I'm using GRUB2 from svn (r2039) with qemu.
Steps I take to reproduce:
1. create an overlay directory e.g. /grub2/overlay
2. populate the directory with
overlay/boot
overlay/boot/grub
overlay/goot/grub/grub.cfg
Where grub.cfg contains some-menuentry for example I use:
menuentry Viengoos {
multiboot /viengoos -D 3 -o serial
module /hieronymus
}
3. run (option1):
$ cd /grub2
$ grub-mkrescue --image-type=floppy --emulation=floppy \
--overlay=overlay grub2-boot-floppy
or (option2):
$ cd /grub2
$ grub-mkrescue --image-type=cdrom --overlay=overlay \ grub2-boot-cdrom
4. start qemu with:
$ cd /grub2
(option 1):
$ qemu --serial stdio -hda fat:kernel-dir -fda grub2-boot-floppy -boot a
or
(option 2):
$ qemu --serial stdio -hda fat:kernel-dir -fda grub2-boot-cdrom -boot d
In the case of option 1, grub2 boots straight to the menu as expected.
Typeing 'c' to get to the prompt then 'ls' at the prompt reveals only
the (memdisk) device.
It was expected that at least (hd0,1) for the -hda fat: partition would
be available
Option: following the above and typing 'ls' at the prompt reveals
(hd0) and (hd96) where (hd0,1) was also expected as above.
qemu version 0.9.1
Thanks,
James Collier

Re: Overlaying default grub.cfg makes qemu fat: partition inaccessible
Quoting James Collier james.collier...@gmail.com: In the case of option 1, grub2 boots straight to the menu as expected. Typeing 'c' to get to the prompt then 'ls' at the prompt reveals only the (memdisk) device. It was expected that at least (hd0,1) for the -hda fat: partition would be available Even without the -hda option, you should get (fd0). I can reproduce the problem with the current GRUB. My impression is that loading grub.cfg stops the initial automatic loading of the modules for the existing hardware. You still can load such modules manually: insmod biosdisk insmod pc After that, ls will show (fd0) and other devices. It looks like a bug to me. -- Regards, Pavel Roskin ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
