Synopsis: VAX11/780 with DEC RM03 on mba0 config file: controller mba0 at nexus ? disk hp0 at mba? drive 0 /sys/vaxmba/hp.c 7.1 (Berkeley) 6/5/86 We had to replace a defective RM03 - after DEC worked on for weeks and it again caught fire they gave up and shipped out a new (refurbished) one. The new one during autoconfiguration reports the drive type as 9775 (!) and so is unusable. I did a lot of poking around in code I don't understand and found that hpmaptype() piddles with the drive serial number hpsn. This seems to be some kludge necessitated by S.I. controllers. At any rate, the serial number of the new drive is 8758. We jumpered a couple of the bits to change it to 8458 or something like that, and then it worked OK. I hope someone wiser than I will figure out whether the driver really is weird, or do we have something else wrong in the hardware that causes the real drive type to be overlooked and activates the S.I. kludge?
