I'd like to run PC-NFS and Clarkson's TN3270 on a PC/AT with a 3C503 (not at the same time). Clarkson's Packet Driver requires the dip-switches set to enable shared memory. PC-NFS's 3C503 driver will not run when I do this; it wants shared memory disabled. I have Geoff Arnold's PC-NFS+Packet Driver Version 2, but I'd rather not run it if I don't have to, since it's officially unsupported. Does enabling shared memory force it to be used, or just set a power-on default that a driver could disable? Why does PC-NFS insist on an inefficient operating mode? According to the documentation, it doesn't do this on the WD8003! -=EPS=-

[...] Why does PC-NFS insist on an inefficient operating mode? The choice was 3Com's, not ours. In PC-NFS 3.0, we added support for the 3C503, 3C523 and 3C505 cards. Rather than doing drivers for each one, we wrote a single driver to interface to 3Com's "vector" interface (one of the precursors to today's NDIS) and obtained vector drivers for each card from 3Com. In theory, this allowed PC-NFS to coexist with 3+ and share the board. In practice, out-of-sync software revisions by Sun and 3Com have made this a somewhat hit-or-miss affair, and in PC-NFS 3.0.1 support for coexistence is officially withdrawn pending further study. I have no idea why 3Com's software uses the 3C503 with shared memory disabled. Maybe it was to minimize software differences between the 501, 503, 505 and 523.
