I succeeded. Grub loads off my USB stick and goes into interactive mode. I spend an hour spinning my wheels in Grub because I forgot the 'sudo' and it wasn't able to see the drives. But, it sent me to gdb and I learned a little more about Grub. And, once I had that solved, it all came together pretty quickly.
In interactive mode, there is no (hd2). But there is an (fd0). This is because the USB drive is 0x00 and since bit 7 isn't set, it is regarded as a floppy disk. I need to figure out how to either remap 0x00 to 0x82 or else force stage2 to address fd0 in LBA mode.
I also tried the 'bootp' command and it said it couldn't detect the hardware. I had compiled in the driver for an older intel 10/100 connection whereas my computer has hardware for a 10/100/1000 circuit. I would think there would be some backward compatibility. But if not, I'll see what I can do.
But those are tasks for tomorrow.
