_________________________________________________________________ STACKER NOTE STACKER NOTE STACKING THE HP 95LX PALMTOP COMPUTER (Applies to Stacker for Windows & DOS 3.0) STAC FAX 3005 (08/19/93) _________________________________________________________________ BACKGROUND The HP 95LX is a palmtop computer that runs under MS-DOS 3.2. It has 1 MB of on-board RAM that is configurable between RAM and disk drive. For example, you could use 256 KB of system RAM and the remaining 768 KB as the C drive. RAM cards vary in size from 512 KB to 1.5 MB. You treat them the same as floppy disks. Each RAM card has its own battery to maintain the data. A slot on the left side of the HP 95LX accepts the RAM cards and is referenced as drive A. You'll have to convert this A: RAM card into a Stacker drive. The 95LX Filer/File Transfer Utility allows file copying, deleting, etc. It also lets you run applications, gives a shell to the DOS prompt, and lets the HP 95LX connect to the serial port on a desktop computer using the Connectivity Pack. The Connectivity Pack enables you to copy files between the two machines. The following procedure involves the use of the Filer and Connectivity Pack, but does not give detailed instruction on their use. Please refer to the HP 95LX documentation. Note An external drive made by PAMCO can connect to a desktop machine via the parallel port; this allows a desktop machine to directly access the RAM cards for the HP 95LX. The current device driver for these drives is NOT compatible with Stacker. PAMCO is currently looking into this situation. PROCEDURE You must use a desktop computer for part of this procedure since the HP 95LX doesn't have enough RAM to run Setup. 1. On the desktop computer, run Stacker Setup to personalize the files and copy them to the hard drive. After this is done, press ESCAPE to end Setup without creating a compressed drive. 2. Then type the following command to build an empty Stacker drive on the desktop computer: CREATE C:\STACVOL.DSK /S=1.5 /R=4.0 This will create a 1.5 MB STACVOL file with an anticipated compression ratio of 4.0 to 1 to accommodate the high compression ratio of Lotus 1-2-3 files. (The /S= specifies the size of the RAM card, in MB. The size may vary depending on the size of the RAM card.) 3. Use SATTRIB to remove the hidden, system and read-only attributes of the STACVOL file with the following command: SATTRIB -R -H -S C:\STACVOL.DSK 4. On the HP 95LX, while in the Filer utility, choose SYSTEM to get to a DOS prompt. 5. Make certain there is no data on the RAM card that is in drive A. 6. At the root directory of drive C on the HP 95LX, add the following line to the CONFIG.SYS file: DEVICE=C:\STACKER.COM A: If there is no CONFIG.SYS file, create one by typing: COPY CON CONFIG.SYS DEVICE=C:\STACKER.COM A: 7. Use the Connectivity Pack on the desktop computer and the Filer/File Transfer utility on the 95LX to transfer STACKER.COM and CHECK.EXE to the root directory of the 95LX. 8. Transfer STACVOL.DSK from the desktop computer to the RAM card in drive A:. 9. Restart the HP 95LX to load the Stacker device driver. 10.Stacker drive A mounts automatically whenever the HP 95LX is restarted with the compressed RAM card installed. _________________________________________________________________ Copyright 1993, Stac Electronics
