Wow! Multi-monitor support (one for Amiga the other for x86)?

Logically only (switch visible monitor via key short cut) and you can only have single custom chipset screen and single RTG-only screen enabled at the same time. ("RTG" = either Amiga RTG board or PC VGA board, not both)

There is no support for simultaneous multiple monitor emulation. Implementing it fully would be quite big task and it still is not worth the trouble.

VGA bios ROM image is also needed.. Is there some generic ones? (If not, at least one that is made for "reference" Cirrus Logic GD54xx ISA board)

There seems to be a BIOS downloadable from http://www.vgamuseum.info/index.php/...ogic-cl-gd5420

Some tweaking to still to do.

Really insane, but in a good way.

Thanks so much for your work, time to spend some Money again.

QEMU includes a VGA BIOS thats GD54xx compatible check: ./qemu/pc-bios/vgabios-cirrus.bin

It does not work (nothing happens). I think it expects QEMU specific features (which I have ripped out).

http://www.nongnu.org/vgabios/ seems to work.

Thats curious as the qemu one is the nongnu.org one, i guess you are right :-)

They can't be identical, qemu one does some extra IO accesses to non-existing ports that are not defined for normal VGA boards.

If you only want to run dos programs, use dosbox. You can try bridgeboard emulation if you want to see how useful (or useless) they were and how they worked, how Amiga-PC integration worked. If you simply want to experience it all

Thanks Toni, but i tell you if i was in a dream i would that atari st and mac games would run with winuae because this is really the best emulator with perhaps dolphin. You did an amazing job !! just the launch of cdda with cdtv emulation which doesn't work for me.

(you know booting on adf and using the cdtv panel to launch cdda)
The rest is perfect !!! I don't know where you find the time to do all this stuff ????

It's really great to have a so good emulator for the amiga.

If i should use emulators like those available for the atari st i could cry.

They are far from winuae.

Awesome, you just saved me a bunch of money Toni - I've always wanted to try the x86 bridgeboards and I was almost motivated to spend for a real hw card to try it

I'll have a play with it soonish, thanks again!

Hello Toni,

I have a problem with Bridgeboard x86 (A1060 Sidecar) expansion and not know the reason.
If I start the PC Mono/PC Color emulation I get a endless loop.
After it show me the RAM and Janus version it start again to check the RAM and Janus version.
No problems with the A2286, A2088 and A2088T expansion.

Toni Wilen · 03 August 2015, 18:22

Set A1060 jumper "System Diagnostics" (which may be inverted in emulation).

Wow, it is working.
Thank you so much!

Toni Wilen · 03 August 2015, 19:53

Remember to change it back in next beta

themamboman · 04 August 2015, 21:43

Any chance someone can post a guide on setting up and using the new pc bridgeboard emulation features, settings and all?

Thanks!

05 August 2015, 01:30

can any one try to answer this?, why can't i open this up from my pc laptop computer?.
