[Coco] Hard drive trouble

[George Ramsower]

Okay...

 I saved h0 and h1 to the hard drive and did this again. Before, I used the 
descriptors I had in the config directory.
 The results were the same except for the DNS setting in /h1.
 Now the cmp looks like this:

OS9[t3]:cmp h0 h1

 Differences

byte      #1 #2
========  == ==
00000013  00 01
00000022  B0 B1
0000002E  03 58
0000002F  C5 D5
00000030  D0 D6

Bytes compared:   00000031
Bytes different:  00000005

Here are dumps of h0 and h1:

OS9[t3]:dump h0

Addr   0 1  2 3  4 5  6 7  8 9  A B  C D  E F  0 2 4 6 8 A C E
----  ---- ---- ---- ---- ---- ---- ---- ----  ----------------

OS9[t3]:dump h1

0030  D6                                       V

When this comes back to me, I'm going to copy it and paste it into a WP 
program or NotePad or WordPad or each to see what results in what I see on 
Hypeterminal and the coco. This email thing makes it all messed up looking.
