[ipxe-devel] Booting different initrd , depending on hardware query pci bus

[Petry Roman, SHS-S IT-TS]

Hello
I use ipxe now for several weeks to boot some thinstation thinclients
over the network. Via http.. works great.. thanks for such a good tool.
I still have one wish 8-)..

Is there a way to boot alternative initrd images depending on the
hardware of the client.. i have some clients which have a nvidia gpu and
others do have ati.. if i embed both dirvers my initrd goes up to
340MB.. with one driver i have only 210 MB..

One way would be to use a pcibus query to get the types.. is this
possible with ipxe ?
The other way would be to use a "better" php script to query a hardware
inventory database and return the right initrd..i would prefer the first
if possible so no more backend hacks are needed.
At the moment my script is simple ..
