[gPXE] Convert TFTP boot to gPXE

[Ben Francis]

I have a netboot system that works over TFTP.  It consists of vmlinuz and
initrd.

I want to convert it to gPXE so it will boot across subnets.

So I put the files on a web server and tried to test from the gPXE command
line:

*gPXE> kernel http://ip-address/gpxe/vmlinuz
*
That command works. However,

*gPXE> initrd http://ip-address/gpxe/initrd
*
just slowly fills up the screen with periods. I tried using the
*append *command
from the working pxelinux setup:

*append ramdisk_blocksize=4096 initrd=/gpxe/initrd root=/dev/ram0
ramdisk_size=144000000 console=ttyS3 splash=silent vga=791
*
but gpxe doesn't have append.

The initrd is about 143MB.

What to do?
