search for: boot_arg

...WS: (and optionally 32-bit kernels with or without PAE.) However, if one doesn't specify boot_kernel_32pae but only boot_kernel_64 and boot_kernel_32, and if the CPU doesn't have support for PAE, args[2] will be executed unconditionally, with no check for if it is defined. Maybe replace boot_args(...: args[2]); with: boot_args(...: args[2] ? args[2] : args[1]); Or maybe some other construct so that the ?: isn't used so many times in a row...

ifgpxe.c32 is a com32 module that will run one command if gPXE extensions are available, and a different command if not. At VMware, we use this module to chain-load gpxelinux.0 from pxelinux.0. Both of those binaries use exactly the same configuration file, and this module allows us to differentiate between the two cases and break the infinite chain-loading loop that might result. Typical usage:

Note: I could simply direct boot the appropriate kernel/initrd to get the alpha1 installation going as always done in the past, but I think this should work. The Debian alpha 1 installer page says it should. Details $ sudo xm create -c wheezytest.cfg Using config file "./wheezytest.cfg". Error: Boot loader didn''t return any data! direct pygrub test run: # pygrub

I need to reliably boot a server from a USB device. Since USB device ordering can be unpredictable, I wrote a simple early-userspace "init" program to find the root FS on the correct USB device & partition. I have "labeled" the root ext2 FS on the USB drive, and the program searches for the label by examining the bytes at a specific offset from the beginning of the
