- Software driver update for Afterburner users
- --------------------------------------------
-
-
- * 68040TOS.PRG (68040 driver - standard TOS version):
-
- Place in the auto folder like this:
-
- XBOOT.PRG boot manager
- 68040TOS.PRG 68040 driver
- 68882.PRG 68882 emulator (if required)
- .... everything else comes afterwards
-
- Notes for TOS users:
-
- ~ This patch will currently not work properly without NVDI - if you
- are using FastRAM. If you do not use FastRAM, then there is no
- problem. The VDI will try to blit data to and from FastRAM as
- soon as the Desktop loads from ROM and the result is nasty looking
- icons and frequent crashes. With NVDI installed, the blitter is
- bypassed and no harm can be done. The patch will be soon improved
- in order to work without needing NVDI.
-
- ~ This version also assumes no SCSI devices are present before drive
- letter 'G'. In other words, C,D,E & F should be IDE (if anything)
- and the rest can be SCSI or even more IDE partitions. Trying to
- use a SCSI drive as letters C->F will probably result in lost data
- if you have FastRAM installed - for the same reasons described above,
- only the SDMA chip is responsible here instead of the blitter. Again,
- non-FastRAM users are not affected.
-
- ~ Anyone wanting a version of the patch to work with SCSI partitions
- BELOW letter 'G' will have to contact me at my email address.
- Eventually, a special configuration program will allow the user to
- set this all up manually and the need for customised versions will
- disappear.
-
-
- * 68040MAG.PRG (68040 driver - MagiC FastRAM specific version):
-
- Place in the auto folder like this:
-
- XBOOT.PRG boot manager - FastRAM flags _MUST_ be set!
- 68040MAG.PRG 68040 driver - FastRAM flags _MUST_ be set!
- MAGXBOOT.PRG MagiC booter - FastRAM flags _MUST_ be set!
- 68882.PRG 68882 emulator (if required)
- .... everything else comes afterwards
-
- Notes for MagiC users:
-
- ~ Nothing must be allowed to run BEFORE the 68040MAG.PRG & MAGXBOOT.PRG
- unless it uses _nothing but_ FastRAM. Use of ST-Ram is strictly off bounds
- until 68040MAG.PRG is executed for the SECOND TIME. I.E. after MAGXBOOT
- performs it's usual warm reset. The reason for this is complicated, but
- if it is not adhered to, the machine will corrupt it's own PMMU tables
- and freeze completely.
-
- ~ If you can't get it working, remove XBOOT (or whatever you use as a
- boot manager), and everything else that you may have set up to run BEFORE
- the 68040MAG.PRG patch program.
-
- ~ There may be occasional problems when attempting a warm boot after MagiC
- has loaded. If this happens (black screen, or rubbish), then just resort
- to a cold start by powering off and let MagiC load again from scratch. It
- doesn't happen often, but can be annoying when it does.
-
- ~ If you use HDDriver, and you have FastRAM installed, then you are advised
- to enable the 'Install XFRB' option in HDDriver. Otherwise interesting
- things might happen to files held on SCSI or Floppy devices! Again, this
- is a bug attributed to MagiC/TOS which should never use FastRAM for DMA
- operations.
-
- ~ If you DON'T have FastRAM, then you shouldn't try to use this patch. You
- should use the 68040TOS.PRG version instead. For non-FastRAM MagiC, place
- the programs in the auto folder like this:
-
- XBOOT.PRG boot manager
- MAGXBOOT.PRG MagiC booter
- 68040TOS.PRG 68040 driver
- 68882.PRG 68882 emulator (if required)
- .... everything else comes afterwards
-
- * 68882.PRG (68040FPU -> 68882 emulator):
-
- This is not required by 68LC040 users. It is only of use to users of
- the full 68040 processor with integral FPU. It emulates a standard
- 68882 co-processor in software with heavy reliance on the 68040FPU.
