SUMMARY: Sbus printer card drivers

Date: Thu Dec 30 1993 - 13:30:07 CST

Earlier, I posted the following to the list:

| I'm doing some work for a neighboring site here helping them to set
| up a small network of Sun IPC's and one SS2. I don't have a lot of
| experience with SunOS (4.1.1 by the way). Anyway, the SS2 has an Sbus
| printer card (lpvi?). These drivers are not a stock part of the kernel but
| they had a tape labelled Sbus Printer Drivers. So I did the
| `extract_unbundled' bit and installed the drivers. The driver code was
| installed via `modload'. We don't have any documentation and there isn't
| anything helpful in the man pages for the drivers. What I'd like to know
| is whether or not I will have to re-load the drivers each time the machine
| is booted. I would have rebooted to find out but people are using the
| machine so why bother? There is a script that was installed
| (SPARCprinterInstall or somesuch) which automates the loading process.
| Should I call this script in /etc/rc before starting lpd?

The response was overwhelming! Yes, you are required to reload the
driver at each reboot. It turns out that the `extract_unbundled' procedure
adds an entry to your rc.local like the following:

# Load SPARCprinter drivers.
if [ -f /etc/load.SPARCprinter ]; then
        sh /etc/load.SPARCprinter > /dev/console

This script loads the necessary device drivers into the kernel.

As it turns out, this was tested last night as there was a power outage
and the machine rebooted when power was restored. The drivers were loaded
and printing still works great!

Thanks for the response!
