4 This release of OS-9 Level One for the Tandy Color Computer 3
|
|
|
5 represents the first community-based release since the discontinuation
|
|
|
6 of both OS-9 Level Two. This release actually takes up where the
|
|
|
7 infamous "Level 2 Upgrade" left off, and incorporates most all of the
|
|
|
8 known features of that never-officially-released version of OS-9.

10 DISTRIBUTION
|
|
|
11 ============
|
|
|
12 There are two single-sided 35 track DSK images ending in '_ss35_1.dsk' and
|
|
|
13 '_ss35_2.dsk' for disks 1 and 2, respectively. This correspondes to
|
|
|
14 the older Tandy method of distributing the operating system.
|
|
|
15
|
|
|
16 The other disk image ending in '_ds40.dsk' is a double-sided 40 track
|
|
|
17 disk image that contains all of the files found on single-sided disks
|
|
|
18 1 and 2. This is useful for those who have double-sided drives and
|
|
|
19 want the entire operating system to reside on one disk.

21 USING THE DISK IMAGES
|
|
|
22 =====================
|
|
|
23 All images will work with Jeff Vavasour's CoCo 3 emulator as-is. If you
|
|
|
24 wish to transfer the 35 track disk images to a 5.25" or 3.5" floppy disk
|
|
|
25 for use with a real CoCo, and have a Linux system equipped with such a
|
|
|
26 disk drive unit, follow the steps below (root login is assumed):
|
|
|
27
|
|
|
28 1. Download and install the latest version of fdutils from
|
|
|
29 http://fdutils.linux.lu/
|
|
|
30
|
|
|
31 2. Once installed, edit the /usr/local/etc/mediaprm file and add the
|
|
|
32 following lines at the end of the file:
|
|
|
33
|
|
|
34 "COCO360":
|
|
|
35 DS DD sect=18 cyl=40 ssize=256 tpi=48 fm=0 gap=8
|
|
|
36
|
|
|
37 "COCO720":
|
|
|
38 DS DD sect=18 cyl=80 ssize=256 tpi=48 fm=0 gap=8
|
|
|
39
|
|
|
40 3. Insert your blank floppy into the drive on your Linux box.
|
|
|
41
|
|
|
42 4. Type the following command:
|
|
|
43
|
|
|
44 setfdprm /dev/fd1 coco (35 Track SSDD floppy disk)
|
|
|
45 OR
|
|
|
46 setfdprm /dev/fd1 coco360 (360K 5.25" floppy disk)
|
|
|
47 OR
|
|
|
48 setfdprm /dev/fd1 coco720 (720K 3.5" floppy disk)
|
|
|
49
|
|
|
50 This assumes your floppy drive is /dev/fd1. You may need to make
|
|
|
51 adjustments to the above commands for your environment.
|
|
|
52
|
|
|
53 5. After typing the setfdprm command, the floppy drive unit should spin
|
|
|
54 for a second then stop. Type this command:
|
|
|
55
|
|
|
56 dd if=<diskimagefile> of=/dev/fd1
|
|
|
57
|
|
|
58 Where <diskimagefile> is the image file you want to transfer to the
|
|
|
59 floppy disk. The image file transfer should start. When it is done,
|
|
|
60 take out the disk and try booting your CoCo with it.
|
|
|
61
|
|
|
62 Repeat steps 3-5 for each additional disk.
