[net.unix-wizards] multibus drivers for Sun Microsystems 4.2 UNIX

avery@mcc-db.UUCP (Jim Avery) (03/07/85)

 I need help in acquiring a source for a Sun Microsystems multibus
dma driver. The reason is that I have to write one and have never done so.
A look at one would help alot. Does anyone out there know of one I 
could get ??????

[Sorry to respond to the list but I couldn't find a useable return
address in the original submission]

	SUN's System Internal's Manual has several examples of
device drivers, and a pretty good description of how to write
them.   If this isn't enough, I can send you a copy of my device
driver for the Pronet ring on the SUN (which does DMA), though I suspect that
at ~1200 lines it is more than you need.
