- INTERSECT Ram Disk
- 11/23/86
-
-
- This is a new and improved rendition (Version 4.0) of the
- public domain INTERSECT Ram Disk Desk Accessory. It has all of the
- capabilities of 3.0 with some improvements to error handling. In
- addition, a new feature in 4.0 will allow your ramdisk to be
- automatically installed whenever you boot your ST. In order to
- have your ramdisk auto install you simply need to select the
- desired size and drive ID then click on the SET AUTO button. This
- will cause a 6 byte file to be written to your boot disk. (If you
- have a floppy based system, make sure that your boot disk is in
- drive A and is not write protected before you press this button).
- Once you create the auto install file your system will boot with
- the specified ramdisk in place. If you decide that you don't want
- an auto install ramdisk you can delete the file INTRAM.AUT.
-
-
- Putting The Ram Disk On Your System
-
- To use this Ram Disk you must place both INTRAM.ACC and
- INTRAM.RSC on your boot disk so that it will be included as a desk
- accessory the next time you start your ST.
-
-
- Using The Ram Disk
-
- To install the Ram Disk you need only click on the INTERSECT
- Ramdisk selection bar contained within the Desk heading of your
- menu. The Ram Disk will the present you with a Dialogue box
- containing the selector buttons for the Ram Disk as well as a
- display of the currently available memory. The size selector will
- also show a suggested Ram Disk size which leaves 128K free for
- programs. The suggested Ram Disk size may be modified by clicking
- on the arrows above and below the digits in the Ram Disk Size
- selector and the Drive designation may be selected by clicking on
- the appropriate drive button. Once you have selected the size and
- drive you must press the INSTALL button to actually install the
- Ram Disk. At that point a tune will be played if the INSTALL was
- successful. In the event that, for some reason, the INSTALL fails
- you will be notified by a tone and message box. The possible
- reasons for failure are:
-
- - Requested Ram Disk Memory size exceeds that which is
- available (Make sure that the Size selected is less than
- memory available).
-
- - Requested Ram Disk Memory size less than that which is
- required for the disk control blocks (Installing a Ram Disk
- of less than 20K is pointless).
-
- - The Drive Specified is already installed in the system (This
- will occur if you have a ram disk or a hard drive currently
- active as the Disk Unit specified when you click INSTALL).
- If you have reset your system with the Ram Disk installed
- you should simply install the Ram Disk by clicking on the
- OK button in the warning dialogue. If, however, you
- actually have an active disk on the specified drive you
- should click on the cancel button, select an available drive
- and click on INSTALL again.
-
- After successfully installing press the EXIT button to close
- the Ram Disk Selector box.
-
- Before you can actually use the Ram Disk you must tell GEM
- about it. This is done by clicking once on any drive ICON (so
- that it is highlighted) and selecting the Install Disk Drive
- selection bar in the Options header of your menu. The Install
- Disk Drive dialogue will be presented. Change the Drive
- Identifier to match the Ram Disk Drive you have installed (D, E or
- F). You may then optionally change the Icon Label to Ram Disk.
- To complete the installation press the Install button an the new
- disk Icon will appear somewhere on the Desktop. Move it to where
- you like and it is ready for use. If you want the Icon to always
- appear automatically when you boot just save your desktop at this
- point.
-
- The Ram Disk may also be set up so that it automatically
- installs when you boot your ST. This is accomplished by creating
- an auto boot file, which can be done from the Ram Disk. To create
- the auto boot for your Ram Disk simply set the drive specification
- and desired Ram Disk Size on the INTERSECT Ram Disk Dialogue but
- instead of pressing the INSTALL button, press the SET AUTO button.
- This will automatically set up the Auto Boot file for your
- ramdisk. Just make sure that your boot disk is in the drive you
- booted from and is not write protected when you select SET AUTO.
-
- To de-install the Ram Disk simply click on the REMOVE button
- and the Ram Disk will be gone and all of the memory that it used
- will be returned to the ST operating system. IMPORTANT: The
- contents of the Ram Disk are permanently lost once you REMOVE it.
-
- To re-install at a later time simply follow the INSTALL
- instructions again.
-
-
-
- Memory Management Limitations
-
- The Memory Management in your ST operating system has several
- limitations that will affect the way that you handle Ram Disk
- Installation as follows:
-
- 1.) When changing resolutions you must first de-install the
- Ram Disk by clicking the REMOVE button. (All data in the Ram Disk
- will be lost at that time so make sure that you have backed up
- anything you will later need). Failure to de-install before a
- resolution change will cause unpredictable results.
-
- 2.) When the Ram Disk is first removed the memory available
- indicator will often not show the total amount of memory
- available. To reclaim all available memory you must run a program
- from the desktop (showing a file will do the job just fine).
-
- 3.) Never install the Ram Disk from within a program unless
- you intend to de-install it before you exit the program. The ST
- operating system will treat the memory allocated like program
- memory and free it when you return to the desktop, the results of
- which are unpredictable. You may however de-install or view
- available memory at any time. In summary, always install the Ram
- Disk from the Desktop and you will not experience this problem.
