A lot. Works well.

You could have a look at the header of the NCR BIOS extension
and check which additional headers (PCI or PnP or whatever) it uses.

For expansion ROMs, this is too much in most cases. BIOSes
tend to ignore ROMs they don't find space for.
(You know, it must be within the ISA hole, even for PCI devs.)

Technically it should be possible, but indeed somewhat hackish.
Since there is normally no EEPROM or so to store configuration
data, it is hard to tell the code whether to netboot or diskboot
in a clean way. The devopen() function is the key point. (And make
sure you disable the filesystems of the other sort - the f_devdata
are different for disk/net.)
