linux options

[MultimediaMan]

This shouldn't be too hard...

Let's walk through the syslinux script:

Code:

label ldiag
    kernel /live/vmlinuz
    append file=/live/filesystem.squasfs boot=live vga=791 initrd=/live/initrd.img ro quiet 2

The only thing getting downloaded directly is vmlinuz... vmlinuz is locating it's next files from kernel arguments, not as initrd downloads.

So, assuming your vmlinuz kernel can follow a URI, you get this in iPXE:

Code:

#!ipxe
set boot-path http://srv1/lenovo-diags
kernel ${boot-path}/vmlinuz
imgargs file=${boot-path}/filesystem.squashfs boot=live vga=791 initrd=${boot-path}/initrd.img ro quiet 2
boot
