Short: Emplant MAC emulation 5.0. LITE RELEASE
Author: Utilities Unlimited International Inc.
Uploader: omen@dartmouth.edu (Omen Wild)
Type: misc/emu
Changes to V5.0 (09/30/94)
--------------------------------------------------------------------------
* New multi-os.device that corrects problems when accessing AmigaDOS
disks. One problem in particular is when starting the emulation
with an AmigaDOS disk in one of the drives, it was possible that the
emulation could crash. Using MultiOSFileSystem with AmigaDOS disks
would cause the drive motor to never shut off, or crash.
* New empser.device. If the two units on the same board were opened
sequentially, the interrupt server would hang. Made a few speed
optimizations.
* New amia.device. Changed a couple of QUICK commands.
* New Jam.library. Got rid of some unnecessary code.
* New EMPLANT.library.
* Made interface more OS2.x compliant by adding keyboard shortcuts to
most functions. The keyboard shortcuts are identified by an
underscore ('_') character beneath the letter to be pressed for the
shortcut.
NOTE: In the MEMORY menu, you can use the -/+ keys to decrease/increase
the MAC System Memory size.
* New RsrvMemV. Corrected a problem with machines that do not have
FPUs.
Changed the reset timing. After installing the kicktag, there was
a delay of 2 seconds before rebooting the machine (first time booting
from a cold boot). This delay is not long enough for some machines.
If the delay is not long enough, the Amiga may not finish its
validation process (which includes writing to the hard drive). The
result is usually a requestor appearing on the next reboot stating
that the boot device is not validated. The delay has been increased
to 4 seconds. Some machines that are fast enough only need a small
delay. You can set the delay to be only 1 second by adding the switch
'-q' after RsrvMemV:
RsrvMem >NIL: -q
* Fixed a problem with HardFileSetup. If the HardFile Type was set
to 'PC-Task' or 'BridgeBoard', and the size of the hardfile was
reduced, the size would be reset to zero (instead of the next number
in sequence).
* Fixed icon image data for floppy devices using multi-os.device with
the emulation.
* Reduced maximum device transfer size to 64K. IDE drives that do not
support block sizes larger than 64K could crash the emulation. MAKE
SURE you select the DMA RESTRICTION gadget (in the DEVICES sub-menu)
if you are using an IDE drive (like what the A4000 comes with).
* Massive re-write of AmigaDOS device support. Fixed some potential
problems with device functions being called with the QUICK bit
set. Added support for auto disk change/write protect sensing.
* Added support for empcd.device.
NOTE: empcd.device is written by Nicola Salmoria, and is NOT included
with the MAC emulation software. It is available via our
technical support BBS, Aminet, and other FTP sites.
* Created 'empdisc.device'. This is a driver similar to Nicola's
'empcd.device', except that it supports ISO 9660 and PhotoCD discs.
You must have AccessPC (control panel) for ISO 9660 discs, and Apple's
PhotoCD init for PhotoCD discs. Technically, any type of CD should
now be usable if you have the proper filesystem handler.
The cache mechanism for empdisc.device was not designed for the best
performance when using MAC HFS discs. It was designed primarily for
ISO 9660 and PhotoCD discs (for the e586DX emulation module). We will
at some point add better cache handling support.
To use a CD-ROM drive from any standard SCSI interface, you will have
to use a sector editor and change the 'scsi.device' to whatever your
SCSI controller's device driver is called (ie. warpdrive.device, etc.).
The default is 'scsi.device' as found on A2091s, A4091s, and A3000s.
* Added support for AmigaDOS removable media devices such as Syquests,
Bernoullis, and CD-ROM drives (using empdisc.device and empcd.device).
Just drag the device into the trash, then remove the media. Now, when
you re-insert the media, it will automatically appear on the desktop
without having to switch to the emulation control screen and click on
'Re-Mount Ejected'. If you throw away a removable device by mistake,
you can just switch to the emulation control screen and click on
'Re-Mount Ejected'. This will prevent you from having to remove the
media an re-insert it.
If you throw away a fixed disk (hard drive partition that is not a
removable media device), you can still use the 'Re-Mount Ejected'
option as before.
* Corrected a major problem with System 7.5 support. The v1.1 and v1.2
256K MAC ROMs are not System 7.5 compatible *at all*. Real MACs with
these ROMs are never going to work with the current System 7.5 software.
Because we are an emulation, we can fix these things. :-)
* Overall cleanup of the emulation's interface code. A lot of the code was
still hanging around from when we used ASSEMPRO.
* New video drivers for PiccoloSD64 video board. NOTE: We experienced
problems with the SD64 and the WarpEngine 40Mhz board. It appears that
moving data too fast to this board will cause problems. If you
experience 'bus errors' while displaying video (QTMovies, etc.), try
running the emulation without using HardKickMMU (this will keep the MAC's
global variables in CHIP memory, slowing things down enough to prevent
the problem from occuring, but also slowing down the entire emulation).
