If your adapter is not supported by RBFG it is not possible to add support
for it. Unless, of course, you have access to RBFG source code and know how
to write PXE UNDI driver for your NIC.
Luckily, Argon Technology can save you this trouble. We offer a PXE on Disk
for many NICs that aren't currently supported by RBFG including the Intel
Pro 100VM.
PXE on Disk works the same way that an RBFG Boot Floppy does by enabling
your client PC to initiate a PXE network boot.
PXE on Disk will interact with any PXE server including the Windows Remote
Installation Services (RIS).

Argon Technology also offers the new and improved RIS Menu Editor (RISme).
RISme extends the capabilities of RIS, allowing you to deploy additional
OSes that aren't supported by default. For example, it possible to use RIS
to perform BIOS updates, deploy Ghost disk images, install Linux, etc.
