iPXE as a chain-load target

[robinsmidsrod]

This is what the "scriptlet" feature does for you. You can load ipxe.lkrn just like any other Linux kernel from grub, and you can specify a command line. The command line is basically a mini-ipxe-script. The most common way to use this feature is like this:

Code:

# Syslinux syntax, can't recall grub syntax
KERNEL ipxe.lkrn
APPEND dhcp && chain http://myserver/boot.ipxe

If you're want to just boot a custom script for each type of ISO you have, then you could do something like this:

Code:

# Syslinux syntax, can't recall grub syntax
KERNEL ipxe.lkrn
APPEND dhcp && chain http://myserver/hiren.ipxe

or you could let boot.ipxe use a variable to boot everything using one script, like this:

Code:

# Syslinux syntax, can't recall grub syntax
KERNEL ipxe.lkrn
APPEND dhcp && set cd hiren && chain http://myserver/boot.ipxe
# in boot.ipxe
sanboot ${cd}.iso
