- Using the BSE Flashdrive with the Atari Portfolio
- -------------------------------------------------
-
- You will need to copy the files: ATFLASH.SYS and ATPART.EXE to the
- Portfolio. Put ATFLASH.SYS in the root directory on RAM drive C:,
- ATPART can be placed on a RAMcard. Connect the Flashdrive to the
- Portfolio using the Portfolio Smart Parallel Interface port. Use a
- cable that is as short as possible.
-
- Preparing the Flashdrive for use:
- ---------------------------------
-
- The Flashdrive hard disk must be prepared before it can be used: There
- are two basic steps to preparing it. First, the drive must be
- partitioned. This defines one or more areas on the disk that will be
- assigned logical drive letters (D:, E:, etc.). The largest partition
- allowed is 32 megabytes, so if the basic capacity of your drive is
- larger than 32 meg, you will need to define multiple partitions to be
- able to use all of that capacity. The second step in preparation of
- the disk is formatting. Formatting creates a directory structure in a
- partition that allows DOS to locate files. Each partition must be
- formatted before it can be used.
-
- Important: If you have formatted your Flashdrive on a computer using a
- version of DOS 3.0 or greater, it WILL NOT WORK properly on the
- Portfolio, which uses DOS version 2.11. You will need to reformat it
- with the ATPART.EXE program before it can be used.
-
- To partition and/or format the Flashdrive, run the ATPART.EXE program.
- After a message describing the configuration of the Flashdrive appears,
- press any key to get to the main menu, where you can choose to create,
- delete, format or view the current partition(s). From the main menu,
- pressing <ESC> will exit the program and return to DOS. If any
- partitions have been created or modified, you will be asked if you want
- to save the changes. If you respond with 'N' the changes you made will
- not be saved. If you press 'Y', the new partition data will be saved,
- effectively erasing any data that may have been on the disk. If you
- choose neither 'Y' or 'N' and press <ESC> again, you be returned to the
- main menu.
-
- Creating a partition: Select main menu option 1 to go to the Create
- Partition sub-menu. There are two types of partitions you can create:
- DOS and EXTended partitions. A DOS partition is limited to a maximum
- size of 32 megabytes. An extended partition may be any size, and
- contains one or more logical DOS partitions of 32 meg or less. The
- first partition on a disk must be a DOS partition. Up to three more
- DOS partitions may be defined, or an extended partition may be defined.
- After defining an extended partition, logical DOS partitions must be
- defined to fill the space it occupies.
-
- After selecting the type of partition you want, the maximum number of
- disk cylinders available to allocate to the partition are displayed at
- a prompt. You can press ENTER to select this default value, or type in
- a smaller number. (When defining an extended partition, always select
- the maximum amount -- you can subdivide the partition later).
-
- Examples of typical partition configurations:
-
- 1. 20 megabyte drive, one 20 meg partition:
- Select the first option: Create DOS partition
- Press ENTER to select the maximum number of cylinders
-
- 2. 60 megabyte drive, three 20 meg DOS partitions:
- Select the first option: Create DOS partition
- Look at the TOTAL number of cylinders on the disk displayed at the
- top of the screen. Divide this number by three and enter the result
- as the number of cylinders to allocate.
- Repeat two more times.
-
- 3. 60 megabyte drive, one 32 meg DOS partition and a 28 meg extended
- partition containing two 14 meg partitions.
- Select the first option: Create DOS partition and use the maximum
- number of cylinders (32 meg).
- Select the second option: Create EXT partition and use the maximum
- number of cylinders.
- Select the third option: Create logical partition
- Take the number of cylinders displayed at the prompt and divide by
- two and enter the result. This will create a 14 meg DOS partition
- in the extended partition. After you press ENTER, you will be
- prompted again to enter the number of cylinders to allocate to the
- next logical DOS partition. This will continue until all available
- cylinders have been used.
-
- If you define four partitions or less, there is no real advantage to
- using extended partitions, and you might as well use four standard DOS
- partitions. However, if you want more than four partitions you must use
- an extended partition.
-
- Deleting partition(s):
- Select main menu option 2 to go to the Delete Partitiion menu. You can
- delete the LAST partition defined, or delete all partitions.
-
- After deleting or creating partition(s), the changes are not actually
- saved to disk until you exit the program, or choose to format the
- partition(s). At this point you have the choice of saving the
- partition data or quitting without saving.
-
- Displaying partitions:
- Main menu option 4 allows viewing the current partition status. You
- can see up to four partitions on the screen at one time. You will see,
- starting from the left, the partition number, the starting and ending
- cylinders of the partition, the partition size in cylinders, and in
- megabytes, and the partition type. If any extended partitions are
- defined, you are offered the option of seeing the extended partition
- contents. A number followed by a + sign at the right shows how many
- logical partitions are in the extended partition. Extended partitions
- do not have a partition number; only DOS partitions and logical DOS
- partitions are numbered.
-
- Formatting a partition:
- After you have defined a partition structure for the disk, you will
- need to format the partition(s). Select main menu option 3 to reach
- the Format Partition menu. Here you can choose to format a single
- partition by number (see Displaying Partitions to find out how to
- determine the number of a partition). Select menu option 1, then enter
- the partition number and press ENTER. The partition will be formatted,
- erasing all data in it. If you like, you can choose to format all
- partitions at once using menu option 2. This will effectively wipe out
- the entire disk data area.
-
- It is possible to run the ATPART.EXE program without changing the
- partition structure if you want to re-format a partition.
-
- Using the prepared Flashdrive:
- ------------------------------
-
- For the Portfolio to recognize the existence of the Flashdrive, the
- ATFLASH.SYS device driver must be installed. This is done by placing
- ATFLASH.SYS on drive C: and editing the CONFIG.SYS file on drive C: (if
- you don't have a CONFIG.SYS file already, you will need to create one).
- Using the Portfolio's built in text editor, add the following line to
- the CONFIG.SYS file:
-
- DEVICE = C:ATFLASH.SYS /P=8078 /T=15
-
- The /P=8078 option tells the driver to use port address 8078 (hex) to
- access the parallel port.
-
- The /T=15 option sets the disk drive timeout delay. This helps save
- battery power in the Flashdrive by turning the motor off when not in
- use. The motor will turn back on automatically when the disk is
- accessed. You can change this number if you want, or make it 0 if you
- don't want the drive to power down automatically.
-
- After saving the CONFIG.SYS file, make sure the Flashdrive is turned on
- and press CTRL-ALT-DEL to reboot the Portfolio. You should see a
- message on the screen describing the disk drive model and serial
- number, as well as a description of the capacity of each logical drive.
- If an error message appears, check the cable connections and make sure
- the Flashdrive battery low indicator is out. After checking the
- connections, reboot the Portfolio again.
-
- The Flashdrive should now be ready for use. Here are some important
- tips for successful operation with the Flashdrive:
-
- When you are ready to switch off the power to the Flashdrive, be sure
- to turn off the Portfolio FIRST. Always turn off the Portfolio and the
- Flashdrive before connecting or disconnecting them. When you are ready
- to switch the Flashdrive on, do so BEFORE turning on the Portfolio. If
- the Flashdrive has been disconnected from the Portfolio, remember to
- press CTRL-ALT-DEL to reboot the computer after turning them on.
