[gPXE] chainloading xxx.c32

[Tom Baumann]

Hello list,

I currently try to chainload the Menu from kernel.org's bko.
But when performing a

chain http://boot3.kernel.org/bko/menu.c32

I always get "Requested memory not available (0x46038001)".

I tried as well with undionly.kpxe.

Version is gPXE 1.0.1.
gPXE 1.0.1 -- Open Source Boot Firmware -- http://etherboot.org
Features: HTTP HTTPS iSCSI DNS TFTP bzImage COMBOOT ELF Multiboot NBI 
PXE PXEXT

How could this being solved?
How will it be possible to chainload the comboot.c32?

Thanks for your help in advance.

Tom.
