[comp.sys.hp] Question on HP disc controllers.

mtsu@blake.acs.washington.edu (Montana State) (04/13/89)

I'm trying to put two hi-speed HPIB interfaces in an HP9000/350 SRX.

I'm going to be adding a couple of disc drives, and since one of the drives
is from a node that is now discless I wanted to pull it's 98625A interface
and put in the 350.  I changed the select code to 26, but when booting
under HPUX 6.0  It finds the new interface, but then panics because
it's not on a 'unique interrupt level'  So I change the Ilevel to 6 and
reboot.  Everything looks good, except that it says it's an
unsupported configuration when it boots.  So how do you really put 2
hi-speed HPIB's in a 350?

re: "So how do you really put 2 hi-speed HPIB's in a 350?"

If they are both late models (98625B, 98262A), just plug 'em in.

If one is an older 98625A (as in your case), set the interrupt level of
the '25A to 4 and the other to 3.

If both are 625A's, set one to 4 and the other to 6.  HP-UX will complain,
but it works.
