Subject: TRS-80 model II boot ROM inquiry

I am looking for information about the boot ROM on the TRS-80 model II,
specifically:

  -- When the system boots, which sectors of the floppy disk in drive A
     are read into which locations in memory?

  -- What is the "Radio Shack format" for which the boot ROM checks
     before it branches to the booted code?  Presumably this involves
     a checksum somewhere.

This data is needed for an effort to customize CP/M for the model II.
(Yes, I know Pickles & Trout make a great system, but they don't
distribute source for their BIOS and there are some additional features
that I've *got* to build.)  If noone has the answers, you'll find me
inside the machine with a flashlight, disassembling the 2k ROM (sigh).
