The normal 23+ boot ROMs do a memory test. This boot sequence can be
disabled via DIP switches on the board. See below.
- CPU (M8189)
- RAM (M8067), 128k*18?
- RAM (8059), same size?
- Floppy controller M8029
- Emulex SC02/C RK06/07 compatible SMD disk controller (for my Ampex
hard drive)
- 2 * M8043 (4 serial ports)
- 1 unknown Plessey interface card, P/No. 701775 (What's that ?)
The SC02 can take optional boot PROMs. Sounds like you have those
installed and enabled. If you haven't done so already, grab the
manual from bitsavers, also grab the 23+ manuals. You will see that
the $ prompt is from the Emulex board (see Section 6). There's
nothing wrong with that boot, if you want to use it. Alternatively,
you could disable that boot and enable the boot on the M8189 board.
One boot or the other, not both.
