boot_scsi.asm: Fix SCSI ID when booting from SCSI
Due to a typo it would probe for SCSI ID 4 instead
of default 0 (or 8 for HDBDOS/SuperDriver).

| 3 *************** | |
| 4 | |
| 5 Welcome to NitrOS-9! | |
| 6 | |
| 7 DISTRIBUTION | |
| 8 ============ | |
| 9 There are two double-sided 40 track DSK images ending in '_ds40_1.dsk', | |
| 10 and '_ds40_2.dsk' for disks 1 and 2, respectively. For those with | |
| 11 3.5" 720K drives, an 80 track DSK image ending in '_ds80.dsk' is also | |
| 12 included in the distribution. | |
| 13 | |
| 14 USING THE DISK IMAGES | |
| 15 ===================== | |
| 16 If you wish to transfer the disk images to a floppy disk for use with a | |
| 17 real CoCo, follow the steps below: | |
| 18 | |
| 19 WINDOWS/DOS: | |
| 20 | |
| 21 1. Download and install the latest version of DSKINI/RETRIEVE at | |
| 22 http://www.nitros9.org/ | |
| 23 | |
| 24 2. Insert a blank double-sided floppy in to your drive (we assume B:) | |
| 25 | |
| 26 3. Type the following command, replacing the name of the image: | |
| 27 | |
| 28 DSKINI /T40 /D B: <diskimagefile> (360K 5.25" floppy disk) | |
| 29 DSKINI /T80 /D B: <diskimagefile> (720K 3.5" floppy disk) | |
| 30 | |
| 31 Where <diskimagefile> is the image file you want to transfer to the | |
| 32 floppy disk. The image file transfer should start. When it is done, | |
| 33 take out the disk and try booting your CoCo with it. | |
| 34 | |
| 35 Repeat steps 2-3 for each additional disk. | |
| 36 | |
| 37 | |
| 38 LINUX: | |
| 39 | |
| 40 1. Download and install the latest version of fdutils from | |
| 41 http://fdutils.linux.lu/ | |
| 42 | |
| 43 2. Once installed, edit the /usr/local/etc/mediaprm file and add the | |
| 44 following lines at the end of the file: | |
| 45 | |
| 46 "COCO360": | |
| 47 DS DD sect=18 cyl=40 ssize=256 tpi=48 | |
| 48 | |
| 49 "COCO720": | |
| 50 DS DD sect=18 cyl=80 ssize=256 tpi=96 | |
| 51 | |
| 52 3. Insert your blank floppy into the drive on your Linux box. | |
| 53 | |
| 54 4. Type the following command: | |
| 55 | |
| 56 setfdprm /dev/fd1 coco360 (360K 5.25" floppy disk) | |
| 57 setfdprm /dev/fd1 coco720 (720K 3.5" floppy disk) | |
| 58 | |
| 59 This assumes your floppy drive is /dev/fd1. You may need to make | |
| 60 adjustments to the above commands for your environment. | |
| 61 | |
| 62 5. After typing the setfdprm command, the floppy drive unit should spin | |
| 63 for a second then stop. Type this command: | |
| 64 | |
| 65 dd if=<diskimagefile> of=/dev/fd1 | |
| 66 | |
| 67 Where <diskimagefile> is the image file you want to transfer to the | |
| 68 floppy disk. The image file transfer should start. When it is done, | |
| 69 take out the disk and try booting your CoCo with it. | |
| 70 | |
| 71 Repeat steps 3-5 for each additional disk. | |
| 72 | |
