NeXT cube fails to boot from SCSI hard disk after apparently successful BuildDisk. I am trying to install FJITSU M2263S SCSI hard disk (600+Mbyte) as the boot disk, and having problems booting off it. I created a disktab entry (see below) and successfully completed BuildDisk on it with no errors. I can boot from OD and manually mount /dev/sd0a and access all the files on the hard disk. But when I try to boot from the hard disk, it gives the following message: NeXT>b b sd(0,0,0) SCSI unexpeced msg:1 sc: Unexpected msg .. (repeated many times, and then gives up booting).. What does this message mean? Has anyone encountered this problem when trying to install a third party SCSI drive into the cube? What am I doing wrong? Jumper setting problem on the drive? "scsimodes /dev/rsd0a" reports as follows: SCSI information for /dev/rsd0a Drive type: FUJITSU M2263S-512 512 bytes per sector 53 sectors per track 15 tracks per cylinder 1658 cylinder per volume (including spare cylinders) 3 spare sectors per cylinder 15 alternate tracks per volume 1312343 usable sectors on volume And the disktab I added for this drive is: # FUJITSU M2263S-512 with 3 spare sectors/cylinder and 512 bytes sectors # M2263S-512|FUJITSU M2263S-512|Fujitsu 760MB w/512 byte sectors as 1 partiction:\ :ty=fixed_rw_scsi:nc#1658:nt#15:ns#26:ss#1024:rm#3600:\ :fp#160:bp#0:ng#0:gs#0:ga#0:ao#0:\ :os=sdmach:z0#32:z1#96:ro=a:\ :pa#0:sa#646230:ba#8192:fa#1024:ca#32:da#4096:ra#10:oa=time:\ :ia:ta=4.3BSD: This disktab gives you the whole disk as one large partition. Another NeXT cube we have is setup similarly with the NeXT's official 660MB drive (Maxtor XT-8760S). SCSI target is set to 1 as "bod" boot messages show as follows: .... SCSI 53C90 Controller, Target 7, as sc0 at 0x2014000 FUJITSU M2263S-512 as sd0 at sc0 target 1 lun 0 Disk Label: MyDisk Disk Capacity 640MB, Device Block 512 bytes .... If you have any clues as to what could be wrong, please tell me. Thank you. Izumi Ohzawa, izumi@violet.berkeley.edu
