A. How to speed up Future Drive Accelerator even more

So you can make Amiga faster.

Install a CopyMem(Quick) (11) Replacement for your processor type:
68000 68020 68040+ The MCP replacement shouldn't be used, because it is slower than these versions.

Set the SCSIsynchron-Flag in the RigidDiskBlock of your boot-harddisk with
RDBFlags.

Don't use ChipMemory as cache, and set not used ChipMem in the preferences, to 100%. See section 7.1 The Mainwindow.

If you use the program PoolMem, start it with the argument NoRamReverse.

A.1 Better use of ATA[PI] drives

You don't have AmigaOS 3.1 and want to install the newest update of the (12) scsi.device to get a better performance? (especially together with ATA[PI] drives)

Attention! There is no guarantee for this hack. (13) The modified file may not be distibuted.

The hack works on an 1200 with OS 3.0.

1. Rename the file `a300.ls.strip', if you use an Amiga 1200 (14) , to `scsi.device', and copy it into the `Devs:' directory.
2. Load `scsi.device' V43.xx into a file-monitor:
   Search for $0c6c0027. The next value is $0014 6516. Replace $6516 by $6026.
3. Get
   AddModule.
   In the first line of your `s:Startup-Sequence' write:
   RUN <>NIL: c:AddModule <>NIL: DEVS:scsi.device CLASS 1 PRI 10 INIT ;V43 CLASS xoper e flags

After the second reboot, the new scsi.device is loaded.

A.2 General speedup for turbo boards

You have a turbo board, e.g. a Blizzard-IV with Extra Fast Memory? Is the exec.library "function-jump-table" (AVL) in the Chip Memory? (Can be found out using XOper or FastExec.)

Get FastExec. Start it with:
FastExec SysInfo

Is the output for SysStkUpper $xxxxxxxx a value greater than
$00200000 if you have 2MB ChipMemory, or
$00100000 if you have 1MB ChipMemory?

If not, then the "supervisor stack" is in Chip Memory. This slows down the "task-switching".

Insert this line in your `s:Startup-Sequence', after AddModule (if present):
FastExec REBOOT FASTSSP FASTMEM
