All VME cards require kernel drivers. The HP-UX k
ernel provides a set of
services in the leset
VME-SERV
which allows the user-pro
vided kernel drivers
access to VME space. Y
ou can use SAM to ensure that the
vme2
driver is in
your HP-UX kernel.
Your vendor should have provided you with the necessary les and instructions
for linking the driver for your card into the HP-UX kernel. Do cumentation
for creating these drivers is contained in the
HP-UX 9.01 VME Driver
Development Guide
(Part Number A2261 90022).
