Re: Problems booting 2.11 on a 11/84

Hi - What CSR do you have the TC13 set for? The Boot ROM did it's job of reading in the 512 byte boot record and transferring control to location 0. The bootblock relocates itself to 48kb which is 0140000. I don't think the problem is cabling in this case. If you have another system that you can view the sources with the file you really need to have in front of you at this time is /usr/src/sys/pdpstand/mtboot.s The section of code where the system is halting (with added octal offsets) is: 0262 bne ctlerr 0264 bit $!1000,hter(csr) / any drive errs except HTER_FCE 0272 beq bumpaddr / no, go bump address ctlerr: 0274 halt The label 'ctlerr' is shared but it indicates that a controller error was encountered out of the 'tmtscom' common logic (shared between the MT and MS drivers): tmtscom: bit $100200,(csr) / error or ready? beq tmtscom / neither, keep looking bmi ctlerr / error - go halt The thing to try is when the system halts looking at the registers (R0 thru R5) _and_ the tape controller registers (starting at 0172520). It's also possible to look at the command buffer being presented to the controller by looking at offset 0460 (0140460). Not sure how useful that will be though. It might be possible to single step the processor starting at location 0 as long as R0 and R1 are set up correctly (R0 has the unit number and R1 the control register address which is 172522 for MS and MT devices).

For example, it claims that 1BSD was derived from 32/V (should have been 3BSD), derives 1BSD from 1BSD and 4.1BSD (should be 4BSD) from the second 1BSD (should be 3BSD), derives ``BSDI'' from 4.3BSD, when in fact BSD/OS is derived from 4.4BSD, doesn't mention System V(.1) or System V.3, etc. And all this is OS code, not networking code.
