QEMU option ROM
Building the ROM image
Check which network adapter is configured for the VM. The default network adapter is the RTL-8029(AS) (PCI ID 10ec:8029).
Build the appropriate ROM image:
cd gpxe/src make bin/10ec8029.rom # for ns8390 10ec:8029
Running QEMU
The -option-rom command-line option tells QEMU to use the gPXE ROM:
qemu -option-rom /path/to/10ec8029.rom /dev/null
This example runs a default VM with no disks and allows you to press Ctrl+B to enter gPXE.
