So, on the Nevada b127 boot attempt (and on Solaris 10 - output is identical), here's the output from "see do-boot" (note that "boot -H cdrom" doesn't seem to make this word available - I have to do a real boot before it loads it and I can see what it's attempting to do):
0 > see do-boot : do-boot parse-bootargs halt? if " Halted with -H flag. " type cr exit get-bootdev load-pkg mount-root zflag? nested? invert and if fs-name$ open-zfs-fs load-file setup-props exec-file ; ok
So, then I type the following:
0 > parse-bootargs ok 0 > get-bootdev ok 0 > load-pkg ok 0 > mount-root seek failed
Can't mount root Aborted. 0 >
Looks like maybe it's failing on mounting the root device? For Opensolaris, I get "Unsupported image format" and the "do-boot" word doesn't ever become available. For Solaris 9, the error is:
FCode UFS Reader 1.12 00/07/17 15:48:16. Loading: /platform//ufsboot Loading: /platform/sun4u/ufsboot Boot load failed. ok
and do-boot looks like this:
0 > see do-boot : do-boot sign-on real-devname halt? if " Halted with -H flag. " type cr exit loader-base plat-booter$ diagnostic-mode? if " Loading: " type 2dup type cr get-file if loader-base def-booter$ diagnostic-mode? if " Loading: " type 2dup type cr get-file if " Boot load failed." type cr exit execit ; ok
In this case, it looks like there are some variables in there, and I'm not sure what to put for them or what it's expecting, nor am I sure what steps I need to try or what to skip.
Thanks - Nick

I assume this is the point where I really need the debugger and the
breakpoints so that I can step through the rest of the boot process piece-by-piece.
Ah - cool. What I'd suggest doing is, right after getting to the ok prompt on boot -H:
ok see do-boot
What you should see is something like what's in the boot.fth from opensolaris: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/psm/stand/boot... lks/common/boot.fth
657 : do-boot ( -- ) 658 parse-bootargs 659 halt? if 660 ." Halted with -H flag. " cr 661 exit 662 then 663 get-bootdev 664 load-pkg 665 mount-root 666 zflag? nested? invert and if 667 fs-name$ open-zfs-fs 668 then 669 load-file ( virt ) 670 setup-props 671 exec-file ( ) 672 ;So, we've already parsed bootargs, let's do the rest of the method manually (skipping zflag stuff, because I presume on a cdrom you don't have zfs).
ok false to halt? \ undo the -H flag just for the heck of it ok get-bootdev ok load-pkg ok mount-root ok load-file ok setup-props ok exec-file
Somewhere in there you'll see failures, which will give you a better feel for what's going wrong. Once you figure out which one it is, repeat the process, but manually executing the method which caused problems. This would be easier with a debugger, but it's still possible without it.
