I try the last bzr repository, but I get the compile error:
cc1: warnings being treated as errors
disk/mdraid1x_linux.c: In function ‘grub_mdraid_detect’:
disk/mdraid1x_linux.c:108: error: ‘sector’ may be used uninitialized in this function

I find the net the hack: case 2 change to default. Then the compiling is OK, but the PC is hang at boot the same way.

The PC-s has an integrated NIC. I try the BIOS upgrade, nothing happend. I 6 months ago use the boot from usb pendrive (PXELINUX, this load PLOP, this load USB pendrvie), it's good.

I use the PXELINUX 1 year ago without problem. If I use the PXELINUX and MEMDISK from PXELINUX everything is doog. If I use then GRUB2 and MEMDISK from PXELINUX, load the boot floppy image, then the PC is hang up.

I'm an IT Manager in High School. In our school is 5 computer room. I
compile the GRUB2, I would like to use the computers by PXE boot
(PXEGRUB).
In 4 computer room is working very well, but in the fifth computer room
the PC-s is always hangs up after I select the menu item.
The bad PC-s has ASUS P5GPL-X SE motherboard.
I try the following:
0. Boot from HDD -> it's OK
1.
insmod biosdisk
insmod part_msdos
chainloader (hd0,1)+1
The PC hang up, the screen is black.
2.
linux16 memdisk (i try all of the options, the result is same)
initrd16 boot2.imz (this is an XP boot floppy image, this work with PXELINUX is very well.)
The PC hang up, the screen is black.
3. In the bios I set the SATA mode to compatible. The memdisk and the chainloader is work very well, but int the compatible mode the HDD is slower.

How can I find, what causes the hang up in enhanced mode?

Sorry my bad english...

Thanx:
