PE1CHL NET and FBB work together under DESQview (or other Multi-Tasker's) with the "G8BPQ Hostmode Emulator" package. The setup is very similar to the method for using the regular BPQ code. Setup your .SYS files in the same and read the appendix on using BPQ mode as well for details.
The following differences should noted.
In INITTNCx.SYS, monitoring is available but you may prefer to use the more comprehensive monitoring within NET instead.
In FORWARD.SYS, "C C SWITCH" will connect the BBS to the NET/ROM in NET, after this point the syntax is specific to NET and the options are :-
A LA2D # P B # C C SWITCH Connect to the switch (Net/Rom in NET) V P 70cm Select the "70cm" port C LA2D Connect LA2D on the port we have just defined # B LA2D F LA2D # ---------
Alternately, you could predefine the downlink to LA2D in AUTOEXEC.NET with the command :-
You would then omit the "port select" line in the above example and the "downlink" would be selected by NET on whatever port you have predefined. This could be any valid NET portname, whether it is an Ethernet or AX/IP encapsulated portname or just another regular port.
You must edit and use BPQCFG.TXT from the G8BPQEMU package and compile it with BPQCFG.EXE which should result in a 3072 byte BPQCFG.BIN file.
You should load G8BPQ.COM (from the emulator) from AUTOEXEC.BAT and this can be loaded high with your favourite memory manager.
You will need to exercise the usual tricks to get the maximum memory from each DESQview window. NET should be started first, to setup the G8BPQ Emulator port mappings, so that Unproto (for TPK users) broadcasts are setup before FBB is booted.
In the autoexec.net file, the emulator will need to be started and the port mapping setup. You should choose port names that differ from the internal names of FBB or BPQ types to avoid confusion, an example is given below.
FREQ USAGE NET-PORT BPQ-PORT FBB-PORT RS232 38400bd A1 1 A 432.675 4800bd 70f 2 B 432.675 1200bd 70s 3 C 144.625 1200bd 2ms 4 D 144.625 4800bd 2mf 5 E 70.3125 1200bd 4m 6 F 50.650 1200bd 6m 7 G Exp. 76800bd exp 8 H
Then you would use the following in autoexec.net :-
This will then map all the above ports to FBB and UI broadcasts will be available on those ports. If you want only selected ports, you could have an INITTNCx.SYS for them and specify if you want UI broadcasts or not. Alternately, an easier method is to specify only those ports you want to map to UI broadcasts as in the above example for NET and only ports setup this way will broadcast UI frames, ports not specified will not broadcast.
The object is to get the maximum memory for FBB and this will always be available in the first DV window. The trick here is to open a dummy window first, as a place holder (a regular DOS one will do fine). Now you should start NET (which will automatically open in window 2) and once this has booted, you will need to switch to the 1st window, close it and then boot FBB. This will release the place holder and give the 1st DV window slot to FBB.
A script that does this automatically is called DESQVIEW.DVS and should be made with the script tools (see DV manual) from this ASCII file :-
{Learn {Shift-F12} "!Startup"} Name the startup script
obd{Enter} Open BIG DOS Window
{DESQ}ont Open NET window
{Delay 5} Wait 5 seconds
{DESQ}s1 Switch to the 1st window
{DESQ}cy Close that window
{DESQ}ofb Open FBB window
{Finish} End of script
This assumes you have the following two letter assignments for windows in DESQview :-
Note there is a delay of 5 seconds to allow NET to boot fully before switching windows and starting FBB, this may need adjusting to suit the speed of your machine.
You will need to make some .PIF files for NET and FBB and the following examples will give you a good starting point :-
You will also set your DMPI allocation for FBB here too. Make sure you allocate at least 2048KB, otherwise FBB may load it's own and waste memory.

1. Open the NET window and then check from the command line to see how much memory is available in NET with the "mem" command.
2. Close NET and allocate another 10KB to the window repeat step 1.
When the amount of free memory does NOT increase, you have reached the maximum and should backoff until you reach the exact point where the free memory starts to drop and add a few KB to that value. (Note this may need adjusting as you upgrade to new NET releases).
1. Open FBB with a large value, say 600KB and reduce in 10KB increments until APPEL.BAT starts to run. Cancel and close the window.
2. Increase the memory by 1KB and repeat step 1 until APPEL.BAT will no longer run then back it off to the previous value.
As with the regular BPQ switch, NET can be setup to handle BPQ ethernet frame mapping. This is achieved through the normal packet driver (for your card) and you need to attach this mapping BEFORE any other mappings to the packet driver in AUTOEXEC.NET :-
