I have a PWS that was set up to boot any of OpenVMS or Debian or WinNT. When powered on, it went to the chevron prompt and you had to tell SRM what you wanted to boot. In other words, set the bootdef_dev variable and the os_type then boot dka0 or whatever. Booting NT required you to use the ARC command.
Suddenly it is coming up in AlphaBIOS and I can't get back to the SRM chevron prompt. I've tried disconnecting the keyboard, mouse, and monitor and putting a VT220 on the COM1 port, but it still boots into AlphaBIOS directly and then boots NT. When I disconnect the drive with NT on it, I still get AlphaBIOS which complains that the drive is invalid.
Even with the SCSI cable disconnected so there are no disk drives (the unit has no internal drive other than the CD and floppy) it goes right into AlphaBIOS.
How do I get back to SRM? Is there a jumper or something to force it back to defaults?
In the past, after it had been running NT it always returned to the SRM prompt after a power off.
The only documentation I can find says to press ENTER during the POST countdown (which isn't displaying on either the monitor or the serial terminal) or to press CTRL-C or CTRL-P to get to the chevron. No results. It also suggests pressing the reset button. That just reboots the AlphaBIOS.
However, upon opening the case to make sure I knew which variation of the Dallas chip I needed, I find that there is in fact a coin cell, easily replaceable once you figure out how to slide the motherboard out. It's a CR2032, looks like that's what I need most likely.
For anyone's future reference, I'll leave the thread here. This is a PWS 433au with the MIATA motherboard, Digital model no. PSPBMLBMIATA
After putting together bits and pieces from several sources, including EISNER and the VMS FAQ, I figured out how to get to SRM and boot OpenVMS in the interim, until I can get a replacement battery.
It's baroque, but it works.
Unplug PC keyboard and mouse. Turn on serial terminal connected to COM1. Then power on. Wait a while, and eventually the AlphaBIOS boot options appear on the serial terminal. Note that the "+" and "-" characters may not display properly in on screen instructions. If it tells you to use " " and " " to change options, use the keyboard + and - on the serial terminal (not the keypad.)
The Fn keys shown on the screen do NOT correspond to the keyboard function keys. Use these:
CTRL-A for F1
CTRL-B for F2
CTRL-V for F3
CTRL-D for F4
CTRL-E for F5
CTRL-F for F6
CTRL-P for F7
CTRL-R for F8
CTRL-T for F9
CTRL-U for F10
CTRL-V for Insert
CTRL-W for Delete
CTRL-H for Backspace
CTRL-[ for Escape
and keyboard + and - to set options
TAB key to move around in menu
Press F2 (CTRL-B) to get to Setup
TAB to "CMOS Setup..."
Press F6 (CTRL-F) to get "Advanced CMOS Setup"
TAB to "Console Selection"
Use + to change to "OpenVMS Console"
Press F10 (CTRL-U) to get back to "CMOS Setup"
Press F10 (CTRL-U) to save changes and exit
Press ENTER to confirm.
Use the RESET button to restart, and you will arrive at the chevron prompt. Now you can boot Linux or VMS, but will have to set date and time. After a power off and on, you may have to repeat this whole operation. Best to replace that battery, I think.

prohorenko February 17 2018 Please help to obtain the license on OpenVMS
malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

malmberg September 10 2017 https://sourceforge.net/p /vms-ports/wiki/VMSInstal lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
DoeveR August 07 2017 Where can I find the write up on running VMS 6.1 using the simh emulator?
