Motorola M810 fun – pt 2

#### warning: this is going to be a semi-long post ####

first off, some drive specs:

187-Bug>IOI
I/O Inquiry Status:
CLUN  DLUN  CNTRL-TYPE  DADDR  DTYPE  RM  Inquiry-Data
   0    10  VME187      1      $00    N   SEAGATE  ST39173N         6244
   0    40  VME187      4      $01    Y   ARCHIVE  VIPER TDC 3800   =07:
   0    50  VME187      5      $01    Y   ARCHIVE  Python 28388-XXX 5.AC

first bunch of problems:
while trying to use bug’s menu option i ran into this little winner:

187-Bug>MENU

1) Continue System Start Up
2) Select Alternate Boot Device
3) Go to System Debugger
4) Initiate Service Call
5) Display System Test Errors
6) Dump Memory to Tape
Enter Menu #: 2

Alternate Boot Device (Controller,Drive,File): 0,0,
Change it (Y/N)? N

Continue System Start Up (Y/N)? N

1) Continue System Start Up
2) Select Alternate Boot Device
3) Go to System Debugger
4) Initiate Service Call
5) Display System Test Errors
6) Dump Memory to Tape
Enter Menu #: 1
RAM      PATS: Patterns.............................. Running --->
PASSED
--Overrun Error--

now you have to take into consideration that it was running a bunch of tests and that this is a 33Mhz machine, so from entering the menu number to error point it takes roughly 7-10 minutes. not to bad though.

so i figured at this point that maybe the physical drive was just not mapped out so i decided to autoboot it with mappings to clun 00 dlun 10 (phys drive):

187-Bug>MENU

1) Continue System Start Up
2) Select Alternate Boot Device
3) Go to System Debugger
4) Initiate Service Call
5) Display System Test Errors
6) Dump Memory to Tape
Enter Menu #: 1
NCR      IRQ: NCR 53C710 Interrupts.................. Running ---> PASSED

Testing Complete
Autoboot in progress... To abort hit <BREAK>
Boot Logic Error
Packet Status: 0300

Autoboot Failed

FUCK!!
so at this point i went in to ENV to change the Auto Boot Controller LUN to 00 and to also change Auto Boot Device LUN to 10.

lets test:

damn.. after some field stripping and investigating, i realized that the disk that was on this machine did not contain the operating system. hmm….. openbsd time!!!

so we now set this puppy up for netbooting making sure that we have a tftp server somewhere on the network:

so now let us netboot this bad boy by issuing a NBO

187-Bug>NBO 00 00

success!!!!

now we just go about installing openbsd as usual.

more updates to come..
