similar to: [PATCH] chain.c32: add support for loading GRUB stage2

Allow the grub loader to (optionally) support using a GRUB menu file. For example chain fs grub=stage2,grub.conf will load GRUB's stage2 and pass the (absolute) path to the file "grub.conf" in the Syslinux filesystem to GRUB's stage2. The path is passed to stage2 in GRUB's device/partition syntax (eg, "(hd0,1)/foo"). Note that we don't check whether the

Grub Legacy stage2 will read the install_partition variable from memory address 0x8208.

If I have a system with two disks, where device.map labels one as hd0 and the other as hd1, and I swap those numbers, the resulting boot sector will differ by one bit.

Here is a patch that makes it possible to chainload GRUB2 core.img form chain.c32. It reuses the grub= parameter (used for chainloading GRUB Legacy stage2): - both loaded at 0x8000 - start execution at offset 0x200 (0x8200 in memory) GRUB2 allows to specify another "GRUB home dir" than the standard /boot/grub GRUB2 doesn't allow to change the configfile 'grub.cfg' name

filename to GRUB Legacy GRUB Legacy reserves 89 bytes for storing the filename of the configfile from memory address 0x8217 to 0x826f. We allow overwriting the default value (/boot/grub/menu.lst) when grubcfg=<filename> is used together with grub=<loader>. Examples: chain.c32 fs grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst chain.c32 hd1,10 grub=/boot/grub/stage2

Hi Folks: I am a NOOB and need some help and/or advice about debugging a domU VM boot problem in XCP 1.0 beta. I am trying to get my first VM installed over the network using XCP 1.0 beta. I am able to get to the VNC boot window but the installation process fails after a few minutes with this error: Unable to retrieve http://10.45.2.1//tcc/os/CentOS-5.5-x86_64/images/stage2.img

My daily AIDE report suggests Grub''s stage2 file has changed. Could I trouble you for your opinion about how concerned I should be and what to do if your concern is moderate or higher?

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

Hello, Lately, I have been working on moving Debian & Ubuntu packages to a stage2 build. This means that, instead of shipping llvm-toolchain packages built with gcc, we are rebuilding everything a second time using the newly built clang. Now, when pushed to Debian, it caused some unexpected issues in particular with rust reported here:

Hello, I'm working on a project which automates creation of EC2 AMI images. To do this, you must use a running EC2 instance to mount an image file in a chroot jail. My problem is that I want to create an AMI that looks exactly like a minimal (nothing selected) install from the CentOS ISO image, but the "stage2" image [1] file is much more "minimal" than that. e.g., it

While playing with some less than usual configurations, I've got bitten few times by geometry settings in case of, usually, microsoft[ish] systems. First two examples, then the improvement idea.
