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.

12 There are three single-sided 40 track DSK images ending in '_ss40_1.dsk',
|
|

|
14
|
|
|
15 The other disk image ending in '_ds40.dsk' is a double-sided 40 track
|
|
|
16 disk image that contains all of the files found on single-sided disks
|
|
427
|
17 1, 2 and 3. This is useful for those who have double-sided drives and
|
|
377
|
18 want the entire operating system to reside on one disk.

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