[ipxe-devel] [PATCH] [prefix] Fix lost command line passed by grub

[Valentine Barshak]

Command line passed to ipxe.lkrn by grub (GNU GRUB 0.97)
seems to be lost and not processed by the ipxe at all.

Looks like the cmdline_size should be set to the maximum value (2047)
instead of 0. BTW, this is how it's set in the Linux kernel.
This change seems to fix the lost command line issue.
