                     54: the motherboard, labeled AUI/Thin. You will need to put the jumpers in

1.2       mspo       81: 
                     82: The SCSI cable in these models is **not** notched to specify which way
                     83: it should be plugged in. The symptom is being unable to boot due to a

                     86: over.
                     87: 
                     88: The only other models that accept internal hard drives are the 362, 382,
                     89: 4XXt, and 4XXs which do not have this uncertainty in cabling.
                     90: 
1.3       ryoon      91: ## What are the Model 362 and 382?
1.2       mspo       92: 
                     93: These models were designed as instrument controllers, unlike the rest of
                     94: the Series 300 and Series 400 systems which were intended as
                     95: workstations or servers. The 362 and 382 are 19" rackmount units with
                     96: very PC-like properties.
                     97: 
                     98: They have 72 pin SIMM slots (with parity on 362, with ECC on 382), two
                     99: SCSI drive bays (usually HD and SCSI floppy), serial, parallel (not
                    100: currently supported by NetBSD), HPIB, sound, HP-HIL, one DIO-I slot, and
                    101: a VGA-style video connector. The 362 has 2 SIMM slots and you can
                    102: install SIMMs one at a time. The 382 has 4 SIMM slots and you must
                    103: install in pairs. Both models accept only 1, 4, and 8 MB SIMMs.
                    104: 
                    105: 382 has three serial ports using the Utility Chip like the Series 400
                    106: models. Only one is accessible unless you build or buy the [special
                    107: cable](#serialsplit).
                    108: 
                    109: 362 has only 640x480 8bpp VGA like graphics chip. 382 was shipped with
                    110: three different graphics chipsets (all 8 bpp): 640x480 at 60 Hz,
                    111: 1024x768 at 75 Hz, and 1280x1024 at 72 Hz. These on-board graphics are
                    112: not supported by NetBSD 5.x and prior, but you can install a DIO-I
                    113: framebuffer and disable the on-board video (there's a jumper on the
                    114: motherboard).
                    115: 
                    116: Since the system was designed as a controller, Ethernet and external
                    117: SCSI are optional and are in the form of a small card that plugs into
                    118: the motherboard. The card is roughly the size of two PCMCIA cards
                    119: stacked together. You can, of course, use a DIO-I Ethernet card.
                    120: 
                    121: Oddly, the motherboard is the same shape and size as a DIO-II card and
                    122: has DIO-II connectors. Jarkko Teppo reports that you can even put the
                    123: motherboard into a normal DIO-II chassis and use it as a "normal" Series
                    124: 300 system. The only problem he encountered was the physical size of the
                    125: Ethernet option. See [Jarkko Teppo's
                    126: report](http://mail-index.NetBSD.org/port-hp300/1999/07/16/0000.html)

                    139: is possible (but unlikely) that it indicates hardware trouble or a
