To: Suns-at-Home@orchestra.ecn.purdue.edu Recently I bought a 501-1045 VME bus SCSI-2 board for my Sun 2/50. The board works fine in a Sun 3, but when I put it in the 2/50 and hook up a Sun 3 disk and tape unit, it will not boot from the tape, giving a sense error instead. It will not boot from the disk, either (it gives an address error), but as the disk has 68020 binaries, this is not too surprising. Is anyone using a Sun 2/50, 2/130, or 2/160 with this SCSI board? Does anyone have any idea what the problem could be? I swapped the memory/VME expansion board into which the SCSI board fits, and the performance was the same. I have two ideas about the cause of the problem, neither of which I can verify at the moment. The first is that the boot routine in the ROM of my 2/50 (ROM revision Q) may be too old to know about the peculiarities of the Emulex controller and tape drive used in the 3/50M-511 mass storage unit. Does anyone have any information about this? The other possibility is that there is a jumper configuration problem on the memory/expansion board that the SCSI board plugs into. This board, the 501-1046, has a jumper, J2100, which is not described in the pages of the Field Engineer Handbook which I have. The traces going to it lead me to believe that it is related to the expansion board connector. Does anyone have any information about the function of this jumper and how it sould be set when the SCSI-2 board is plugged into it?

A Sun 2/120 serving a diskless 2/120 is not a pretty sight. -Dan Muntz dmuntz@caen.engin.umich.edu ------------------------------ Date: Mon, 20 Nov 89 13:21:02 -0500 From: curt (Curt Freeland) Subject: Suns-at-Home Digest V2 #25 To: Suns-at-Home-List@orchestra.ecn.purdue.edu, A couple of items: In V2 #25, dmuntz writes: ------------------------------ Date: Sat, 18 Nov 89 11:57:22 EST From: dmuntz@caen.engin.umich.edu (Dan Muntz) Subject: Sun 2/120 Disks and more To: suns-at-home@orchestra.ecn.purdue.edu I'd like to put a ~300 meg SCSI drive in my Sun 2/120 and I'd like to hear about any systems out there that are configured this way (what brand/model of drive, what controller, switch settings, etc.) I was also wondering if there is any way to make the video board in a Sun 2/120 "happy" in the far right slot in the cage. If I move it to any slot but the one it's in (2 from the right I believe) then it won't work. There are some dip switches and jumpers on the board. -Dan Muntz dmuntz@caen.engin.umich.edu The video board in a 2/120 also contains the "memory bus" terminators. Slot 1 (far left) is the CPU, then you have 4 memory slots, then the next slot is where the video board should reside. These slots all use the "P2" connector as a private memory bus. If the video board is not in slot 6, you need a memory terminator board in there. I suppose you could also put the video board in slots 2 through 5, but you are not really terminating the memory bus correctly when you do that. As far as the switches, and jumpers, there are 2 different SUN 2/120 video boards. One is a model 501-1003 (1 dipswitch, 2 rows of jumpers), and the 501-1052 (no dipswitches). Sounds like you have a 501-1003. The following is for that board (from the SUN Field Engineers Manual): J1903 (Serial interrupt level select) 1-2 out, 3-4 out, 5-6 out, 7-8 out, 9-10 out, 11-12 out, 13-14 in, 15-16 out. J1904 (Video interrupt level select) 1-2 out, 3-4 out, 5-6 out, 7-8 out, 9-10 in*, 11-12 out, 13-14 out, 15-16 out. * Used for Diagnostics must be in to run video tests U100 (base address select) 1-7 off, 8 on (0x700000) I have a 2/120 at home and this is how I am set up. All works fine.

To: Suns-at-Home@orchestra.ecn.purdue.edu Does anybody know if a xy451 can be used in a 2/120? I've tried a number of jumper options, but keep getting lost interrupts. Thanks for any help... Yes, we are running a xy451 in a 2/120. It is installed in slot 8, and is set up identically to our 451's in SUN3 and SUN4 servers. I left it in 24 bit addressing mode, so I can swap it without worrying about different switch settings.... The setup is: JC 1-2 out (enables 16 bit addressing mode) base address of ee40 JA 1-2 in (address bit F) 3-4 in 5-6 in 7-8 out 9-10 in 11-12 in 13-14 in 15-16 out 17-18 out 19-20 in 21-22 out 23-24 out 25-26 out (Address bit 3; in for address ee48, out for ee40) JM 1-2 in (16-24 mode for VME-bus) JK 1-8 in for VMEbus (24 bit address jumpers ADR0x17--ADR0x14) JX 5-6 in all others out (Interrupt request level) INT2 JY 1-2 out (Bus Arbitration BPRO) JH 1-2 in (AC power down protection) JZ 2-3 in (Common Bus request disabled) JN 1-2 in (activity indicator) JD 1-2-3-4 out (-5VDC from backplane) JE 1-2-3-4 out (-5VDC from backplane) JG 1-2 in 3-4 in (-5Vdc from backplane) JW 1-2 in (Busy not synchronized to bus clock) Good luck getting it to run.
