Boot OpenVMS from the disk image in test/run-axpbox to verify end-to-end guest operation (SRM boot command, bootstrap, SYSINIT, startup to login). Use for deep verification after CPU/disk/timing changes.

Boot OpenVMS (full-guest verification)

Media lives in test/run-axpbox/:

openvms8.4-ww-welkom012.img — 6 GB pre-installed OpenVMS 8.4-2L1 system disk (boots from IDE as dqa0)
ALPHA0842L1.ISO — OpenVMS 8.4 install CD (attach as ATAPI CD, shows up as dqb0)

This folder is gitignored. If the files do not exist, prompt the user to place them.

Never boot the user's image directly — OpenVMS writes to its system disk. Copy it first:

mkdir -p test/vms && cd test/vms
cp ../../test/run-axpbox/openvms8.4-ww-welkom012.img vms-disk.img

Config: test/vms/es40.cfg (memory.bits=28, ali_ide disk0.0 = vms-disk.img, disk1.0 = the ISO read-only as cdrom, serial on 127.0.0.1:21000, skip_memtest_hack=true for speed).

Automated run

test/vms/bootvms2.py drives the whole flow over telnet: waits for P00>>>, sends boot dqa0, answers the VMS date prompt (DD-MMM-YYYY HH:MM), and waits for a login-ish marker.

cd test/vms && pkill -9 -x axpbox; sleep 1
[ -f cl67srmrom.exe ] || wget -q -O cl67srmrom.exe 'http://raymii.org/s/inc/downloads/es40-srmon/cl67srmrom.exe'
../../build/axpbox run > vmsrun.log 2>&1 &
sleep 6
python3 bootvms2.py dqa0 900 vmscon.log     # ~4 min to full startup
pkill -9 -x axpbox
sed 's/\x00//g' vmscon.log | tail -30

What a good boot looks like

boot dqa0 → "block 0 of dqa0... is a valid boot block" → "jumping to bootstrap code"
Banner: OpenVMS (TM) Alpha Operating System, Version V8.4-2L1
Please enter date and time (DD-MMM-YYYY HH:MM) — the welkom image prompts on every boot (TIMEPROMPTWAIT); the script answers.
DECnet, OPCOM, AUDIT startup messages with correct current timestamps (verifies the TOY/timezone plumbing), license warnings (normal for an unlicensed image), "Startup processing continuing...".

Boot takes ~3–5 minutes on the interpreter. The whole run fits within a 900 s script timeout. bootvms.py (same dir) is the shorter variant that stops at the OpenVMS banner.

Cleanup: the 6 GB vms-disk.img copy is disposable and gitignored — delete it when done if disk space matters.

port-from-es40

lenticularis39/axpbox

Port upstream ES40-Emu commits into axpbox. Use whenever the user asks to bring in, sync, or port changes from the es40 repo (github ES40-Emu/es40, local clone to /tmp/es40). Covers delta computation, wholesale-replace vs manual patching, the axpbox invariants (std:: threading, .hpp, clang-format, rebrand), and the verification gates.

srm-boot-test

lenticularis39/axpbox

Run the headless SRM firmware boot test (boots to P00>>> over telnet and diffs the console log). Use after any change to CPU, chipset, serial, or firmware code, and always once per verified stage of larger work.

2026-07-10204

test-arc

lenticularis39/axpbox

Boot the ARC/AlphaBIOS console from a pre-programmed flash image with the S3 Trio64 on the SDL window. Use to verify the ARC/Windows-NT path (flash boot, nvram auto-arc script, S3 graphics).

2026-07-10204

verify-vga-sdl

lenticularis39/axpbox

Visually verify the S3/VGA/SDL render pipeline (framebuffer dumps, SRM-on-VGA text check) and test mouse/keyboard input paths. Use after graphics, GUI, S3, or input changes, or when a guest's VGA output needs inspection on a headless/WSLg host.
