    I am looking for C/Assembly routines to place an IBM Token Ring card
    into promiscuous mode so that I can strip out the headers.

As far as I know, IBM specifically designed all of its standard Token Ring
adapters so they cannot be placed in promiscuous mode under any circumstances.
This is a "security feature".  IBM does have a special "Ring Monitoring"
interface, but when I last asked, they weren't willing to provide any
programming information (it is used by their own ring monitoring products).
Most other vendors' 802.5 cards use the TI chipset, and can be placed in
promiscuous mode given the proper firmware (frequently supplied as PROMs
by the board vendor).
