Does anybody know where I could acquire a PCI-bus card that has a switch or
button to force a blue-screen? I thought OSR used to sell them, but didn’t
see 'em in the store.
Something like http://www.connecttech.com/dumpswitch_microsite perhaps?
I don’t know these folks, but that’s what Google turned up for me.

Here is how to program the PAL:

You could just glue the chips on and existing PCI card.

There are 3 alternative solutions to a PCI card:
-
Some motherboards include the NMI-button function, you just have to
wire the relevant jumper to a front panel button. -
You could write/modify a custom driver which calls KeBugCheckEx in
response to a signal on an unused “legacy” serial (use the CD line) or
parallel (use the ??? line) port. Both pieces of legacy hardware can be
programmed to trigger an IRQ when that pin is shorted to ground by a
button (you may need a pull-up resistor in the plug and to set another
pin high in the driver to provide power for that resistor). -
Some versions of the i8042prt.sys standard driver for the PS/2
keyboard port can be configured to BSOD when a specific key is pressed.
Note that methods 2 and 3 will not work while interrupts are disabled
with CLI or in the APIC. Method 1 and real NMI boards should though.
Quality debug boards also include a small 2 digit display which can be
set with a single WRITE_PORT_BYTE() operation at a well known address
defined by the PC architecture (Can’t remember which one though).

Thanks guys, I usually use #3, but in this certain case the keyboard is USB.

You can use USB keyboards with Vista and later

And with 2003 there is a hotfix:

You are a better googler than me.

I’ve never actually had to use it on a USB keyboard machine personally
yet, but I always point clients to the fact that Microsoft makes this
available for USB too (via kbdhid instead of i8042prt) in post-Server
2003 SP1 and in Vista and 2008. I’ve never tried it to see if its
supported for USB in XP SP3, but worth checking.

The lame part about this is that kbdhid has no ISR, so the bugcheck happens
at IRQL DISPATCH_LEVEL. This is not at all as useful as the PS/2 keyboard
version, which bugchecks at DIRQL.
