- Introduction
- ============
-
- PatchBlizzardMem patches your Blizzard accelerator's Fast-RAM, enabling the
- ramdrive-device to use it for RAD disks.
-
- The ramdrive-device uses only memory marked as "KICK" (the includes call it
- "memory that can be use for KickTag stuff"), and Blizzard Fast-RAM does not
- have this attribute.
-
- This patch searches the memory nodes for memory named as "Blizzard_Mem",
- and adds the KICK attribute to it. This causes several problems, namely
- that RAD disks created in this memory are not recoverable after a reset
- (unlike normal RAD disks), and the machine will hang after exactly one or
- two resets, depending on whether or not the boot-menu is used.
-
- Nothing "bad" will happen, you'll just have to do another reset when it
- hangs, but at least it's quicker than deactivating a recoverable RAD!
-
- The patch does not survive a reset, so it has to be run each time the
- system is restarted (if the patch is to be used).
-
- Pros
- - You don't have to keep typing 'remrad force' or switching off the
- machine for 10 seconds to remove an unwanted RAD (as long as it's in
- Blizzard_Mem).
-
- Cons
- - The RAD(s) will not be recoverable.
- - The machine will hang after a boot-menu use or two normal resets
- if the machine has been reset with a RAD still in Blizzard_Mem.
-
-
-
- When to use this patch
- ======================
-
- - When you want to have a RAD disk in your Fast-RAM (Blizzard_Mem).
- - When you want to use more than one floppy-sized RAD (and don't have enough
- spare Chip-RAM).
-
-
- When not to use this patch
- ==========================
-
- - When you want the RAD to stay resident in memory
- - When you want the RAD to use Chip-Memory
-
-
- Usage
- =====
-
- PatchBlizzardMem [QUIET]
-
- If run without the QUIET keyword, a requester will pop up reminding you of
- the effects the patch will have on your system, and will report on its
- findings.
-
- The patch can be run again to switch the memory back to normal.
-
-
- What if the patch doesn't work on my accelerator's memory?
- ==========================================================
- Mail me - I have only been able to test it on my machine (A1200 Blizzard II,
- 40MHz '030 + 40MHz '882, 5MB Fast-Ram). It has only been tested on WB3.0
- but should work on WB2 just as well, and on lower versions but without the
- requester, although I am unaware of any Blizzard accelerators for anything
- other than the AGA generation of Amigas (WB3).
-
- I'm particularly interested to hear from other people who find this patch
- useful, and people who would find this patch useful if only it worked on
- their machine! If you have a Blizzard board and the patch doesn't work,
- mail me as much detailed information as you can - use SysInfo to view the
- name of your Fast-RAM (eg. "Blizzard_Mem"). The output from ShowConfig
- would also be very useful.
-
- It is also possible that this patch could be modified to patch other types
- of accelerator's memory which exhibit the same symptoms. If the RAD won't
- go into your Fast-RAM, mail me as much info as you can (ie. SysInfo &
- ShowConfig) and I'll update the patch.
-
- This patch only operates on the first area of Blizzard_Mem it finds,
- although it's no major rewrite to ammend this if anybody has a problem with
- it.

-
-
- Thanks to William F. Maddock for the giving me the idea for this program!
