Monitor format for ProFiles

Do you recall what the ProFile showed up as in the Devices list? I am using Monitor 12.3 on a Lisa2, and all I get are DRIVE1 and DRIVE2, with DRIVE2 being the 'working' device. Any attempt to communicate with DRIVE1 just hangs the system. That said, there does not appear to be a way to unmount the 'working' floppy device to load additional resources. Access to a ProFile would be handy here.
I assume the guide you're referring to is this? http://www.bitsavers.org/pdf/apple/lisa/pascal_monitor/The_Pascal_Development_System_Manual_Feb82.pdf
Page 57 mentions using a ProFile, but not booting from one. But, it does mention 'Transfer all of the files on the female boot diskette (to the profile)', so I dunno.
Anyway, I can't see my ProFile to even Zero it out.

I'm afraid I don't remember much that's useful here --- I guess I just let this project fall by the wayside! I have a distant memory rattling around in my head that you have to mark the drive as being attached to the system somehow (something like mounting in Unix), but I really can't recall anything useful. Sorry about that!
stepleton:
Rereading, I do remember copying the system files to the ProFile at one point with high hopes that it might do something to enable booting from the hard drive, but it didn't work in my experiments.
I'd forgotten about the odd gendered terminology that the documentation uses: there's the word "male" for little-endian (and hence the 6502-powered Apple II is "male") and "female" for big-endian, which, well, "Lisa" I guess. It was important to talk about these things because you could apparently have Monitor setups where a Lisa and II could be connected together. It sounds like you would use the II to get the ball rolling, which I suspect was a more common thing to do as the Lisa hardware was still under development.
PDF page 4 also drops unhelpful hints:
--- Quote ---To boot from a diskette based Apple II, first power up the Apple II with the male boot diskette in drive #4:. Insert the female boot in drive #5: and power up the Lisa. The female boot volume can also reside on a hard disk. SYSTEM.STARTUP on the male boot volume automatically executes MONBOOT, the program that starts up the Monitor on the Lisa. If you type space during the boot process, MONBOOT is not executed. If you type 'D' during the boot process, the debugging version of the Monitor is booted.

It still sounds to me like disks on the Lisa side are just used for data storage here and not booting.

That's OK with me, as long as I can change the working device to the ProFile vs floppy. I need to play around with it and see where that attachment point happens. Thanks for the tip!

Is it possible that since 12.3 is a point release, and seems to be the only one for Sony drives, that DRIVE1/DRIVE2 refers to the old Twiggies and that 12.3 was a quick and dirty hack to add Sony compatibility? I seem to remember some piece of software somewhere that still refers to the Sony drive as the "lower floppy" which is where the second Twiggy drive was in the Lisa 1.
