I would appreciate if someone can tell me what the latest versions of Aread
and Awrite are. The files that I currently have are:
aread.exe 10608 1/1/80 6:41a
awrite.exe10560 1/1/80 6:47a.
As of yet, I can't get either of these two programs to read/write to a
virtual device (using jlink). For example if I jlink c: d1:pc/ibmdisk, where
d1: is a hard drive on the amiga side and the file pc/ibmdisk contains
several files written on the ibm side (dir c: works great). If I try
awrite c:file.txt vd0:file.txt, a file of the file.txt is created on the Amiga
side but is of zero length. After running awrite if I again dir c: I get a
read fault on drive c, abort, retry, ignore. I have gotten aread/awrite to
work correctly if the IBM files are on the floppy connected directly to the
bridgeboard.
On the same topic does anyone know if Commodore will ever release a
version that in addition to the above problems also allows for wildcard
file specs? Has Commodore released the information needed for someone outside
of Commodore to write such a program (eg how does one talk to teh amiga side
PCDisk program)?

FSS works well and there are many improvements in Janus software but: 1) The documentation is incomplete (I have learned where to find the speaker and external controler connectors from a German magazine) 2) The system hangs from time to time witout apparent reasons. 3) When I boot with PCDisk running on the amiga side the PC screen is continually trashed with error messages 4) Some software which must be booted from a floppy (and does it well on every PC I know) does not work with the bridgeboard (a boot error message is displayed) Well, my enthusiasm dimnished somehow now.

Unfortunately, he took the word of someone on the net who detailed how it could be done, and it doesn't work. He did some playing and found out how to do it, and has written it up for TransAmi #6. He has kindly given me permission to cross-post a message from Compuserve with the methodology, so here it is: --------------------------------------------- #: 32034 S13/Tool Box 25-Jan-89 00:55:35 Sb: #32003-Disk Sector Editor Fm: Don Curtis/SYSOP 76703,4321 To: Andre Frech(CBM/ATL) 72077,3301 Andre, It'll be in my article for Transactor for the Amiga, issue #6, but in a nutshell: 1. partition via FDISK and ADISK as per normal if you don't already have a JANUS partition. 2. If you do have a JANUS partition, backup the entire thing. 3. Use DJMount and DPFormat and look at the start and ending cylinder numbers output by DPFormat...they're important. 4. Once formatted, use a sector editor and change byte #4 of track 0, sector 0 from 00 to 01 (change fs type to DOS1). 5. reboot...do NOT use DJMount any more 6. Create a mountlist for FFS, for JH0: (first partition) Unit # will be 0, JH1: (second partition) will be Unit 1, etc. You can call the drive anything you want to...nothing magical about JH0: and so forth. 7. Use the low and high cylinder numbers reported by DPFormat for LowCyl and HighCyl. Device is jdisk.device, sectors, tracks, etc. to match your specific drive. 8. Otherwise, normal FFS mountlist 9. Now MOUNT the drive...it'll work fine under FFS The one exception...and the reason for the gyrations is that the normal Format command will hang on the first cylinder no matter how the drive is mounted...thus you have to play with the dos type indicator by hand. It will now run significantly faster...as in 4 to 5 times as fast and as is typical with FFS drives, will hold an extra 5% of data. Typical disclaimer...I figured this method out, tested it and it worked fine for me...your mileage may vary.

The new Janus allows you to create an Amigados file which can be used by the bridgeboard as a bootable (or not bootable if you prefer) drive. There is a program on the Janus disk called 'MakeAB' which will format that 'file' to simulate any hard disk you can imagine. It works very nicely. An added advantage is that it is a normal file to AmigaDos and can be backed up, renamed, deleted, etc like any other file. If you have a real hard disk running with the bridgeboard you can also partition it to have an AmigaDos partition which is accessable from the Amiga side. It will be a bit slower in access due to having to pass the data through the bridgeboard. Terry

Yes it is possible to autoboot the BridgeBoard PC from an Amiga hard drive. I believe you need version 2.0 of the Janus software, because that is what I am using. 1.) Go to partition where you want the PC hard drive to be. 2.) Use the 'MakeAB' command to generate a file which simulates the PC hard drive. 3.) In the PC/Systems drawer create a file called Aboot.CTRL which states the complete path name where the psuedo PC hard drive (file) exists (i.e. dh3:pchd) where pchd is the file created using MakeAB I think that will do it.

What of the 5 1/4 drive it comes with, does that have an external case or is
it purely internal???
Thanks!

Here are some questions that, it seems, nobody around here can answer about
the AT bridgeboard. Hopefully, someone in NETLAND has one and can answer.
1. Which slots (in a 2000) are taken up by the installation of the bridge-
board? An amiga slot? An AT slot? One of each?
2. If I wanted to add external monitor (in conjunction with the bridgeboard)
for VGA capabilities, could I just pop in an IBM VGA card and add a VGA
monitor? Would this work?
3. What type of IBM cards will work well with the bridgeboard? What about
something like the ADLIB or SOUNDBLASTER music cards?

the AT bridgeboard. Hopefully, someone in NETLAND has one and can answer.
1. Which slots (in a 2000) are taken up by the installation of the bridge-
board? An amiga slot? An AT slot? One of each?
Because of the daughterboard on the AT Bridgeboard the installation takes
up 2 slots. Whether they include the other AT slot or the next Amiga
slot depends on which where they are installed.
2. If I wanted to add external monitor (in conjunction with the bridgeboard)
for VGA capabilities, could I just pop in an IBM VGA card and add a VGA
monitor? Would this work?
Yes, you can install a VGA card and it will work. I recommend getting one
of the cards listed in the 2286 manual since they have been tested by CBM.
You also have to set up PCPrefs to turn off the normal Amiga output to the
windows. A lot of confusion occurs when people first do this because they
can see the IBM side but can't type in it. In order to enter the IBM side
you must have one of the console windows open and active on the Amiga side.
I usually just activate the PCMono window for this.
3. What type of IBM cards will work well with the bridgeboard? What about
something like the ADLIB or SOUNDBLASTER music cards?
Most cards should work fine with the Bridgeboards. The ones that don't tend
to be ones that access COM2 which I believe CBM has taken the interupts for
their own use.

Subject: AT Bridgeboards
The AT Bridgeboard takes up both an Amiga slot and a PC slot. As a result,
it has to be placed in one of the two positions where these slots overlap.
Yes, you can just drop in a graphics card (VGA or other) and connect it to a
monitor and it will work. The Bridgeboard manual lists some cards that are
guaranteed to work, but in general anything that works on a real AT will work
on an AT Bridgeboard. The only thing to keep in mind is that Amigas are only
shipped with 2 AT slots; the other two slots are 8-bit XT slots. Since the
Bridgeboard itself takes up one slot, that leaves room for 1 AT add-in card.
If you want, the Amiga motherboard is designed to allow you to solder in 2
additional connectors to convert the XT slots to AT slots, but that takes a
little extra work.
According to the Bridgeboard manual, most PC cards will work fine. About the
only source of problems is the interrupts used by the PC-Amiga connection.
Apparently some accellerator cards use the same interrupts and hence won't
work with Bridgeboards. Other than this, I've never heard of any problems.
The only add-in card I've used is a serial port card, and I had no problems.
Now, if I've convinced you that the AT Bridgeboard is awesome, I just happen
to be selling mine. Seriously. Everything I've said above is true, I just
have decided that I have more use for a laptop than a Bridgeboard, so I'm
selling mine (or trading for a laptop). If you're interested, I'm asking
$900 or best offer, and I'll even throw in that serial card (I forgot to
mention it in my post to comp.sys.amiga).

The bridgeboard is the bridge between the Amiga part and the PC part, so
it installs in one of each. You can choose one of two places, depending on
how many Amiga/PC slots You need. The two PC slots on the far left (seen
from front of machine) can easily be made into At slots (soldering of sockets).

Yes. You can then run in parallell on the two monitors. Just make the PC
window that always (?) shows up on the Amiga side as small as possible to
make it slow down as little as possible. One MultiScan monitor and switching
of the monitor cable between the VGA card and the Amiga is also possible
(9-23 pin adaptor necessary).

Most cards that don't use the same interrupts as the Amiga/PC communications
will work. (Most 386 accelerators don't work because of this).
