Emulation of bridgeboard 2088XT with WinUAE

No. But someone probably should start by creating pile of test disks that play sounds automatically

SYS:PC/system/PC.boot contains text strings concerning the aboot.ctrl file.
PC.boot seems to be 8088 code, certainly loaded at startup by the janus.library.

Janus x86 side is properly loaded, it can be seen in your screenshot.

I have set run >NIL: SYS:PC/pcdisk in the startup-sequence just after the bindrivers command.

Which Janus version? I think PC service stuff changed completely in later Janus versions.

Perhaps the bios are not really 2088XT... don't know how to diagnose or debug that.

v3.5 = 2088 Bios. Wrong bios would crash or early boot self tests would fail.

I expected to find a 8088@4,77MHz, it shows NECV20@10,4MHz and it is really more nervous than PC-Task.

Dosbos core is minimum 286 but it shouldn't cause any problems.

@Toni It is the Bridgeboard disk, sell with the 2088XT card in 1989
Janus Handler 2.63
Janus Library 33.1
It is noted RJ Mical 2.1g in the about of PCWindow (PC Mono or PC Color)

SYS:PC/pcdisk service is used for awrite and aread msdos/janus commands but also with the pc.boot/aboot.ctrl

Perhaps I should upgrade... with janus.library v36.83 ?

I don't know. Unless you have confirmed working config (from confirmed working real installation 1:1 copy), I don't really care if it works or not, it could be normal that it does not work. Sorry

Works for me (at least it worked). Installed janus (don't remember which version) created aboot file, don't remember more.

[AnnaWu]

I use the last version of Janus.
Everything (ABoot, AT IDE, XTIDE Universal, VGA, .../depending on the x86 Bridgeboard model) is working/bootable for me.
Special thanks goes to Toni.

[Toni Wilen]

It is possible no one has tested old janus with "old style" aboot system.

[Gilloo]

Don't search anymore, there was 2 things wrong

1) in the header file of my hd file
ABOOT + 3 zeros
Heads 0x0004 (max 0x0010)
Sectors 0x0020 (max 0x0040)
Cylinders 0xffcc (max 0x0400)

The Cylinders value is wrong, it must be 0x01fc instead 0xffcc
4*32*460*512 + 512 = 30147072 (30MB)

2) in the startup sequence, the following must be present
BindDrivers
run >NIL: SYS:PC/PCDisk
run >NIL: SYS:PC/AMouse
run >NIL: SYS:PC/Services/TimeServ


All is right
If you remove the 512 header, the aboot file becomes a classic .hdf or .img file.
If anybody is interressed, I can provide a tool to check, fix, add or remove this block.

Little by little...

PCDisk ok
TimeServ ok, but MSDOS3.30 is not Y2K compliant...
AMouse... windows and mouse dependent programs hang up.

Check the older thread, maybe it is helpful.

keyboard :
alt shortcut are not supported...
i.e. left alt + 92 = \

I don't see how this is related to emulation, there is no keyboard microcontroller in XT systems (only AT and later) that could cause this, it is all done in janus software or in dos.

In fact yes they are supported, but it must be done slowly: left alt then one second after type the wanted number on the keypad
On the other hand, the numlock key seems to do nothing.

Concerning the mouse, the amouse.com wait for the amouse service via the 11 interrupt, and wait it for a while...

[Toni Wilen]

"Works for me" which means (as usual): test case is required. Test case that matches exactly. Preferably "boot from this hd using this config, open pc window, type amouse". Nothing like "do this and do that and then something else and perhaps something happens or perhaps not".

Hi Toni,
Here's some work for you...

hdd_13_bb.zip

A2000_13_bb.uae

hdd 13 bb is a 20MB hdd image done with
workbench 1.3 (french)
extras 1.3
bridgeboard 1.3

need: 1.3 rom and A2088 BIOS 3.6.1 380788-06.bin

Inside dh0:, there is a hd image of a complete set of janus and msdos 3.30 which were with the 2088XT package.
Just click on System1.3, open PC, launch PC Color then
type amouse in the msdos window.
amouse hangs, (but atime works (with a wrong date, but it is another story of Y2K bug...))

On the pc hd there is a tools directory with msd.exe inside.
This M$ tool works well with the amouse.com on a true bb 2088XT.

Tell me if something missing...

[AnnaWu]

The AMOUSE.COM (PC side) driver is working, tested on Volkov Commander and Star Commander.
Before don't forget to switch the mouse:
Amiga: Left Amiga + P
PC : Insert + P

Example: A2088 Color AB HDD.hdf > TheZone!

[Gilloo]

@AnnaWu thanks.
@Toni Concerning amouse, don't search anymore there are bad versionning between my PC janus software and the amiga side. I need something between 1.2 and 1.7... I will try with
the good disk

To fix the Y2K bug... 1900+116 = 19116

New update in >TheZone!<

I have some questions, how do you do to create dos floppy images without using WinImage, only with free tools? How do you copy external files to the ms-dos floppy image, what tools offer this feature? And finally, it is possible to do this all using only AmigaOS software?

The floppy PC-MSDOS you can create with WinUAE and also wanting to format from AmigaOS (see screenshot), for copying Floppy you can use DOS commands, but if I remember correctly, there are also tools to AmigaOS.
