Large ROM images
A PXE ROM
If you enable large numbers of iPXE features, you may find that the ROM becomes too large to use. Some network cards cannot support ROMs larger than 64kB, and some BIOSes may fail to complete their power-on self-test (POST) when larger ROM images are present.
You may be able to use a .mrom image to alleviate some of these problems. A .mrom image appears to the BIOS as a very small (3kB) ROM, which contains only a small loader stub. The full iPXE image is loaded only when the BIOS attempts to boot from the network card.
You can build a .mrom image by simply changing .rom to .mrom. For example:
make bin/808610de.rom # Normal .rom image
make bin/808610de.mrom # .mrom image |
