Bridgeboard emulation (x86 CPU, for example A2286)

[Arnie]

Using A3000 2386+ATIde HD + 16mb bridgeboard mem crashes WinUAE just as WB has loaded. 4,8,32 & 64 no crash.

I'm unable to match the amount of memory with the bios after 8mb, is it possible to use more than 8mb?

For some reason Disk2 of the Win95 Install set isn't recognised at all, any idea why? The disk is O.K, it works in VirtualBox.

http://aminet.net/docs/hard/A2386_16MB.lha includes BIOS patch instructions. (I haven't tested it)

I do not think it's a memory problem, System requirements for installing Windows 95: 4 megabytes (MB) of memory (8 MB recommended), I too did not recognize the floppy 2.
To me Windows 95 it is installed perfectly (folder setup CD), i only had a few problems at the restart of Win95 "preparation Windows" as mentioned HERE

Fixed. DOSBox SVGA framebuffer, (not needed by UAE), address was not set, default value caused it to be mapped at 16M.

WinUAE crashed on booting Win95. Logs attached for debugging.

(logs2.7z is the second attempt at booting with logs enabled)

EDIT: I get an error message after a crash "No timer Tick Interrupt"

[AMIGASYSTEM]

I have not had the crash, even now when I try to start Windows 95,It hangs in the usual place without having a crash !

[Arnie]

Did you manage to add a CD drive for Installation? I used the ATIde second port.

[AMIGASYSTEM]

No, I simply took the folder "setup" from CD di Win95, and then I copied nell'hardfile PC (1Giga), with WinImage It was enough a simple drag and drop, it took only a few seconds , see screenshot

Hi! I just wanted to post a quick note about something that's been driving me batty for days now. I finally figured out that to get the x86 VGA RTG emulation to work properly requires that 32-bit color depth be selected in the Display settings panel. Otherwise, I get only mostly-blank VGA screen with a few dots and lines. Is there some reason that 32-bit color depth should be required for VGA RTG to work, or is it a bug that it fails to work if 16-bit color depth is selected, at least in my setup? Has anyone else had this problem?

I have already mentioned it few times in this thread. Affects VGA text mode only.

http://www.winuae.net/files/b/winuae.7z may fix it (not tested).

Thanks for the fix which is working for me.

Thanks, I guessed it right

Run with -log (log window visible), do you get lots of disk access log messages when you insert disk 2 and press return (or whatever it asks to press)?

Attach at least that part of log.

The Windows 95 disks (apart from the first I guess) are in DMF format, maybe WinUAE doesn't support that yet?

Yes confirm, Disk 1 (1.440 KB), Disk 2/3/../13 (1.680 KB)

That is not supported and not going to be supported for a while. Not worth the trouble. (Only standard PC format is supported, no "raw" format is supported)

EDIT: If difference really is only number of sectors/track (smaller gap), then it should be easy to support.

[Toni Wilen]

http://www.winuae.net/files/b/winuae.7z may or may not support DMF disks. If only difference really was 21 sectors/track.

Ok Toni, not yet tested the Windows side, but the Amiga side Floppy PC-MsDos (1.680 KB) drives are mounted perfectly

EDIT
OK, Even from MS-DOS (1.680 KB) floppy is visible

Another nice work, Toni.

Cool. Next on the list to implement () is support for the somewhat weirder XDF format as used on IBM OS/2 installation disks. There must be someone bored and/or masochistic enough to try installing OS/2, right?

By the way, that page also mentions DMF, saying its sectors are interleaved. And it seems Microsoft have a patent describing the DMF format. PDF of that uploaded to The Zone for convenience.

No, thanks. It can't be supported by standard disk image format (variable sector sizes).

Plain image won't support interleave either and probably no software cares.
