[sebhc] HDOS boot/space bar question.

Hi Barry,

I'm not talking about the "H: Boot", but after that step. With a CP/M
disk, after "H: Boot", the H89 boots all the way to a command prompt.
For HDOS, I just verified three different behavior with three
different HDOS 2.0 disks (On the same H89 without changing any
dipswitches). For the first one, the light comes on, then goes off. (I
initially thought the disk was bad.) After a few space bar presses,
the prompt: ACTION? <BOOT> comes up. Options are either BOOT, CHECK,
or HELP. Pressing 'B' continues the boot until the date prompt. Enter
the date, and the next prompt is the command prompt. The second disk
does not require the spaces, but immediately gets to the "ACTION?
<BOOT>" prompt. Then it continues as the first disk did. On my third
disk, I do the "H: Boot", it SKIPS the "ACTION? <BOOT>" step and
immediately displays the HDOS banner and the first prompt is the date,
followed by the command prompt.
