I am investigating the possibilities for adding TCP/IP capabilities
to a PC/104 based embedded system which will run DOS and the RTKernel OS.
The aim is to boot up the diskless system with an application from a
bootp/tftp-server.
Because of this I am trying to find (or develop code for) a PROM for
booting the system remotely with bootp/tftp. The Ethernet hardware on
the PC/104 board is a smc9000 family (SMC91C92) controller cicuit.
While pursuing this line I have found the FreeBSD netboot facility
and Terry Lamberts advice
(http://lake.canberra.edu.au/pub/samba/digest/1995/95apr/0147.html).
Since the FreeBSD distribution of netboot didn't hold code for the
SMC91C92 device, some searching got me a FreeBSD device driver (half
way?) at the FTP site of SMC (ftp://ftp.smc.com/pub/chips/smc9000/smc9bsd.tar).
Before I sit down and try to incorporate selected parts of this
device driver in netboot, I would like to ask the following questions:
-Have anyone tried to implement support for the
SMC91C92 device in netboot?
-Have anyone seen a similar thing somewhere else?
-Have anyone experience from fitting netboot for
boot of DOS (or RTKernel) applikations?
Thanks in advance
