I bought my H89 used with a 100K Hard-sectored SSSD drive and
running HDOS. Everything was great until I ordered CP/M for it
a few months ago. After a series of hardware upgrades and bad
disk exchanges, I have a disk that I think works, it just doesn't
always work.
Most of the time, when I try to boot CP/M, I get the 2 line header
about HEATH CP/M 2.2x03 for H17 drives, etc., then...
BDOS ERROR ON A, SELECT: and then anything else I try to do I get
ERROR DURING WARM BOOT, PRESS ANY KEY and any key I press, I keep
getting that.
But...
I have also gotten the following messages when booting (after the
2 line header):
INSERT DISK D IN DRIVE D: THEN HIT RETURN
G G
C C
B B
H M <-- !!
A A
E E
I I
The wierd part is hitting return after the C in C and the E in E
messages will get CP/M to boot CORRECTLY. All the others just give
the regular BDOS ERROR ON A:, SELECT message. It seems to have something
to do with what disk is in it before hand, because I can try to boot
a non-bootable disk, then try to boot CP/M again and it'll usually
do something different.
Once I do get CP/M booted, everything is fine, I can read all other
CP/M disks and make back-ups and everything. No, I can't boot the
backup I make of the system disk, I thought about that, too. I have
looked at the rotational speed of my disk drive, and while it was a
little outside the recommended tollerance, correcting it has no apparent
effect.
I'm hoping someone can read through all this and say "oh, yeah, i saw
that happen once before!" That's the only way I can see my being able
to fix it, otherwise I guess I'll have do drag it to San Antonio
(the nearest Heath Service Center).
ANY help anyone can give will be GREATLY appreciated.....Thanks.
