The "1B101B10" magic number indicates a failure from calling 
install_block in arch/x86/prefix/libprefix.S.  The only possible failure 
here is a CRC32 checksum error on the source ROM image.

There are various places where the source ROM image could be located at 
this point, depending on the capabilities that the BIOS reported to 
iPXE.  These are indicated in the startup banner line, e.g.:

   iPXE (ipxe.org) 00:03.0 C980 PCI2.10 PnP PMM+07F924C0+07EF24C0 C980

What does the startup banner line say on your system for the 3c905B?
