[comp.sys.sun] Ciprico Rimfire as bootable device

jamieson@rutgers.edu (steve) (09/06/89)

We have just received a Ciprico Rimfire controller and a Fujitsu 2382.
Currently the system boots from a Xylogics 450/451 at address ee40. We
also would like to load SunOs 4.0.3 on the new disk. Will SunOS recognize
the Ciprico controller as the bootable device if we change the Xylogics to
address ee48. How will munix recognize "rf" as a controller type ? Can we
leave the Xylogics as primary bootable device and have the Rimfire as
secondary in order to have two bootable operating systems ?

Any ideas welcome. thanks

I have performed the following exercise on a Ciprico RF3223 with a Sun
688MB disk attached with the Sun cables:

1. run munix and format xy0 (really rf0, but it worked)
2. run miniunix from the b partition and install 4.0 with root on
   xy0a (Generic kernal boots and runs at about the speed of a real
   xy451)
3. install 4.0.3 upgrade on xy0
4. build a custon kernal with support for "rf" and root on rf0.
5. boot new system (still from xy(0,0,0)...). The kernal loads, the
   rf configures, and the disk suddenly speeds up as the rf driver starts
   to do its thing rather than the xy driver.

It seems that the Ciprico emulation is COMPLETE in that it not only
allows one to call the thing an "xy" all the way through running multi-
user, the emulation also slows the disk down to where it would be with
a real xy451. I like the controller.
