[HECnet] RSX-11M v4.1 SYSGEN - OK, I give up - what am I doing wrong?

[Bob Armstrong]

; The response to the following question specifies the highest interrupt
; vector.   If you respond with a value less than or equal to 400, SYSGEN
; will assign the value associated with the highest interrupt vector
; specified during the Peripheral Section.   Therefore, if your system
; will include devices that are not specified during the Peripheral
; Section and which have vectors above 400 (devices such as K-series and
; certain communication devices), specify that value in the next question.

  0 .LE. 400 ....

(14) Highest Interrupt Vector.   The default is zero (0).   I am pretty sure
that must be changed to reflect the hardware installed.

    I'm trying to SYSGEN an 11M 4.1 system from the distribution on

I'm taking
pretty much the default answer for everything.   The build
seems to go
without error and yet the resulting system crashes as soon as it 
boots.   I give up - what am I doing wrong?   Somebody give
me a clue, please!   The simh log is attached.

When RSX is building the system, it at one point creates the new 
system image to run, called [1,54]RSX11M.SYS.

The relevant line is

PIP RSX11M.SYS/CO/NV/BL:498.=RSX11M.TSK

Now, your machine only have 128kW. That is 256 kByte. Of this, 8 kByte 
goes away because of the I/O page. Leaving 248 kByte. This is 496 disk 
blocks.

It *might* be that your disk file is too big, making the system assume 
that it can place stuff in memory that don't exist. RSX11M.SYS is 
pretty close to just a memory dump.

Try creating a new RSX11M.SYS, which is a bit smaller, and then rerun 
the VMR command, and try booting that file instead and see if that 
helps?
