[Blindapple] I created am amdos 3.5 disk

[joseph.norton at gmail.com]

Hi listers:

 

Ok, got the disk updated.

 

Now, it has all the files it's supposed to have.  I did include a patched
version of fid per the instructions on the disk, so you don't need to patch
it yourself, unless you just want the experience.

 

Anyway, here's a link to the utilities disk for amdos:

Here's a link to the 800K disk image I created.  As mentioned before, it
features the files from TexTalker 3.1.2 for DOS 3.3 in the first 400K
partition, then, the second 400K partition is empty.

Now, here are the notes on AMDOS which explain how it works.  These can also
be accessed by running the viewer program RUN.ME, from the AMDOS utilities
disk.

 

                              AmDOS 3.5 User Notes

                                 by Gary Little

     

                                [Release 861016]

     

     AmDOS 3.5 (Amateur Disk Operating System version 3.5) is a modified

     version of DOS 3.3 that works with the UniDisk 3.5, Apple 3.5 Drive,

     or any 3.5" drive connected to Central Point Software's Universal Disk

     Controller (as well as standard 5.25" drives, of course). To install

     it, boot DOS 3.3 (or a similar operating system like ProntoDOS or

     Diversi-DOS) from a 5.25" disk or a hard disk, enter a BRUN AMDOS.LOAD

     command, and then, when asked to do so, specify the slot number of the

     controller card for the 3.5" drive. (This is 5 if the drive is

     connected to the external drive port of a IIc or a GS.) Alternatively,

     you can boot AmDOS directly from a previously initialized 3.5" disk,

     just as you would boot DOS 3.3 from a 5.25" disk.

     

     To initialize a 3.5" disk, LOAD an Applesoft "greeting" program into

     memory and then enter a BRUN AMDOS.INIT command. After you press the

     space bar to clear the user-supported program notice, enter the slot

     and drive number of the disk to be initialized and then the name of

     the greeting program you loaded. Next, insert the disk to be

     initialized and press "I" to begin the procedure. Initialization takes

     approximately one minute.

     

     AMDOS.INIT partitions an initialized 3.5" disk into two distinct 400K

     volumes; there are 50 tracks per volume and 32 sectors per track. Use

     the ",D1" and ",D3" drive parameters (as well as a slot parameter, if

     necessary) with your DOS 3.3 commands to select the first and second

     volumes of drive 1. Use ",D2" and ",D4" to select the first and second

     volumes of drive 2. For example, to catalog the second volume on drive

     1, use the command "CATALOG,D3". As with DOS 3.3, if you don't specify

     a slot or drive parameter, the most recently specified value is

     implicitly used.

     

     AmDOS increases the number of directory sectors per 400K volume from

     15 to 31, meaning the directory has room for 217 file names, rather

     than the usual 105. The directory occupies sectors 1 to 31 of track 17

     and the sectors are linked together in the following order: from

     sector 15 down to 1, then from sector 31 down to 16.

     

     AmDOS Memory Usage

     

     AmDOS uses one data area in the high end of memory: $BEAF to $BFA7.

     Don't use any DOS 3.3 program that uses this reserved area or your

     system won't work properly. If you press Reset when the drive light is

     on, the area from $BCDF to $BCFF (a popular area for DOS patches)

     could be overwritten too, so avoid pressing Reset.

     

     AmDOS Disables the INIT Command

     

     With AmDOS installed, the INIT command is disabled. If you need to

     initialize a 5.25" floppy disk, you must first boot a disk containing

     an unmodified copy of DOS 3.3. To re-install AmDOS after booting DOS

     3.3, enter a BRUN AMDOS.LOAD command.

 

     Using FID with AmDOS

     

     You must modify the FID utility program on the DOS 3.3 system master

     disk before it will properly transfer files to and from AmDOS-

     formatted 3.5" disks. Modifications are necessary because standard FID

     supports drive numbers 1 and 2 only, and it doesn't work with volumes

     having capacities above 200K.

     

     Here are the steps to follow to make the necessary modifications to

     each of the two released versions of FID:

     

     FID (on IIe System Master)       | FID (on II Plus System Master)

     ---------------------------------|---------------------------------

     ]UNLOCK FID                      | ]UNLOCK FID

     ]BLOAD FID                       | ]BLOAD FID

     ]CALL -151                       | ]CALL -151

     *0854:A9 78                      | *0854:A9 78

     *0973:B5                         | *0973:B5

     *09BF:B5                         | *09BF:B5

     *11ED:4C 89 16                   | *11ED:4C 89 16

     *1414:B1                         | *1414:B1

     *1689:8D 32 19 B9 8C 19 8D 33 19 | *1689:8D 31 19 B9 8B 19 8D 32 19

     *1692:B9 8D 19 8D 34 19 0D 33 19 | *1692:B9 8C 19 8D 33 19 0D 32 19

     *169B:0D 32 19 4C F2 11          | *169B:0D 31 19 4C F2 11

     *3D0G                            | *3D0G

     ]BSAVE FID,A2051,L4687           | ]BSAVE FID,A2051,L4686

     

     (To determine which version of FID you have, enter PRINT PEEK(5277)

     after the BLOAD FID command. If the printed result is 168, you have

     the IIe version; if it is 211, you have the II Plus version.)

     

     To automate these steps, first transfer a copy of FID to the AmDOS

     5.25" master disk from the DOS 3.3 system master disk (using FID

     itself!). Then enter the command EXEC PATCH.FID.IIE (if you have the

     IIe version of FID) or EXEC PATCH.FID.IIPLUS (if you have the II Plus

     version) from Applesoft command mode.

     

     Relocating AmDOS to the Language Card

     

     Any program that relocates standard DOS 3.3 to the 16K language card

     RAM area will work with AmDOS. The DOS relocators that come with

     Diversi-DOS and ProntoDOS also work. Be aware, however, that you can

     only use AMDOS.INIT or AMDOS.LOAD before DOS has been relocated.

     

     Using AmDOS with Hard Disks

     

     Most DOS 3.3-compatible hard disk systems will work with AmDOS,

     including The Sider and the CMC "Quick" series. Just be sure to BRUN

     AMDOS.LOAD after booting the DOS 3.3 partition of the hard disk.

     

     Using AmDOS with RAMdisks

     

     Most RAMdisk drivers that don't use AmDOS's reserved memory area will

     work with AmDOS (the only known incompatible drivers are older

     versions of the Diversi-DOS RAMDISK program). This includes the

     drivers for MultiRAM, RamWorks, and the Apple 1M Memory Expansion

     Card. After installing a RAMdisk driver (other than the three just

     mentioned) it's a good idea to BRUN AMDOS.LOAD to re-install AmDOS,

     just in case the driver disconnects AmDOS. This is necessary if

     the RAMdisk driver installs itself by placing a JMP (jump)

     instruction at location $BD12 without saving and chaining to the

     JMP put there by the AmDOS installer.

     

     Using AmDOS with the Universal Disk Controller

     

     If you're using one 5.25" drive and one 3.5" drive with the UDC,

     attach the 3.5" drive to the drive 2 connector so you can boot copy-

     protected DOS 3.3 programs on 5.25" disks from drive 1. (DOS 3.3 won't

     boot properly from drive 2.) Unfortunately, you can't boot AmDOS

     directly from the 3.5" drive in this situation --- to install AmDOS,

     boot DOS 3.3 from a 5.25" disk and then enter a BRUN AMDOS.LOAD

     command. (Note: If the 5.25" drive doesn't seem to work after you

     access the 3.5" drive, your UDC needs a ROM upgrade; contact Central

     Point Software for further information.)

     

     Using AmDOS with Diversi-DOS

     

     AmDOS works with both the 48K and 64K versions of Diversi-DOS, but you

     can only use AMDOS.INIT and AMDOS.LOAD before BRUNning DDMOVER to

     install the 64K version. AmDOS does not work with the utility programs

     GARB and BUFFER, or with versions of RAMDISK prior to the one released

     with version 4.2C of Diversi-DOS. You cannot boot the 64K version of

     Diversi-DOS (as modified by AmDOS) from a 3.5" disk.

     

     About the Author

     

     AmDOS was developed by Gary B. Little, author of the Point-to-Point

     communications program (Pinpoint Publishing) and three books on how to

     program the Apple II: Inside the Apple //e, Inside the Apple //c, and

     Apple ProDOS: Advanced Features for Programmers (Prentice Hall Press).
