- Page 1-5 in the DDG suggests these references:
-
- EISA Configuration Guide for HP-UX, part number B2370-90000
- Dealer Configuration File Creation Guide, part number D2230-90001

- The id is read from the eisa card (at offset 0xC80 in its I/O space)
- and passed into your attach routine (first argument). Is this what
- you're talking about? Or are you asking how to create the id to be
- programmed into the card? There might be some algorithm, but I think
- it's also OK to choose a random 32-bit integer, since the chances
- of collision with another vendor's id are small.
