OK thanks Toni

And it must support SCSI CDROMs too. (better option than trying to add some extra IDE hack)

EDIT: PCem has some 53C400 based SCSI controller supported (53C400 is emulated in WinUAE) so this is one choice if it is sane enough SCSI controller and BIOS ROM is vailable.

Hy Tony,
scusme if don't aswer before, but not all day i can read the forum.

_A) I Confirm have the bios Bootable (Test with pcem)

_B) I Confirm that it isa Adaptec AHA-1542C

_C) I Confirm the support Cdrom (i Test in pcem)

In The zone have upload at:
_A) Bios
_B) Datasheet
_C) Dos Driver
_D) Aspi Driver for Windows 9.x (With 95 i have tested with Win 98 No)

Memory Possible Conf:
_Adress: 130 - 134 - 230 - 234 - 330 - 334

_Bios Andress: C8000 - CC000 -D0000 - D4000 -D8000 - DC000



Conf CdRom for Dos and Windows 3.11

_Into config.sys add:
__DEVICE=C:\DOSDRIVER\ASPI4DOS.SYS /D
__DEVICE=C:\DOSDRIVER\ASPICD.SYS /D:CDROM0


_Into autoexec.bat add:
__C:\DOS\MSCDEX.EXE /D:CDROM0



....i ready for all test.

I did say that it must have UAE supported SCSI chip. None of Adaptec chips count. I won't debug some alien SCSI emulation using PC software!

....is only controller SCSI emulate in Pcem.
I Think that copy and paste code from pcem to winuae.

But if not possible. Ok....i Try

[LanceT]

Still following this
HWIFO shows as ATAPI device.

tried MTMCDS.SYS
Error I get is "CDR101: Not ready reading drive."

Will keep trying different drivers.

[LanceT]

Silly me don't know why I didn't click next screen LOL

[Toni Wilen]

Next step is to enable scsi logging (ATAPI uses SCSI commands): run winuae with -log -scsiemulog -scsilog command line parameters. If driver expects something unexpected or some rarely used SCSI command needs to be implemented. PC is totally different world than Amiga after all

[LanceT]

Using the IDE:0 (auto) as above I did manage to get to boot a cd-driver from a dos disk (x86 side) and then was able to read the directory contents of a Win98 ISO disk. After that I tried to use the same driver to boot from my HD file, that was a no-go can't even get x86 or workbench to see the iso now. Will try again in the morning.
The driver is "sjcdapi.sys" sanyo v1.33 atapi may have been a one off or triggered by trying other drivers first.

Toni, if you you are looking for a BIOS which PCem supports, pls tell me.

P.S. Thanks for the fix (chdman)

i have found a driver; ATAPICD.SYS
With this driver funtion correcty on dos, on windows 3.11;
Windows 9x don't have need of driver and funtion correcty.

XT Primary - With Master HDD and Slave CD-Rom

For Dos and Windows 3.11
Add into Config.sys
DEVICE=C:\DRIVER\ATAPICD.SYS /D:CDROM

Add into Autoexec.bat
C:\DOS\MSCDEX.EXE /D:CDROM

In TheZone i have upload a driver atapicd.sys

Good Looky!

Thank you Zilog, That worked great.

Now to get out my old rusty PC. CD's

[Zilog]

Hy Tony,
i try tu use under Window95 a Cd-Audio and winaue crash.

In Atacch Files.

I don't see anything bridgeboard specific -> test and confirm if it happens in plain AmigaOS.

EDIT: also include winuaelog.txt from bridgeboard crash using following command line parameters: -log -scsiemulog -scsilog -logflush

Hi Toni - can you clarify for me if the new bridgeboard code supports anything better than a 386 .. or can it also simulate the modified A2386SX boards as discussed in http://aminet.net/package/misc/emu/BBCpuUpgrde1.0 ?

[AnnaWu]

Audio CD on WfW is working well.
Peter Gabriel Karaoke (CD+G*) image. *Can play Audio data only because this is not a (Karaoke)player to present graphics.

[AMIGASYSTEM]

What does it mean "WfW", someone can tell me why HardFile "VGA IDE Primary HDD Boot WfW" they work well with "AT IDE Primary (86)" while i HardFile "XTIDE Universal BIOS HD" they are not support system boot "AT IDE Primary (86)"?

WfW = Windows for Workgroups 3.11
The rest is not clear for me. IDE Primary and XTIDE Universal are completely different.

ATAPI (IDE CD) uses SCSI commands. Don't try to analyze any command line parameter names..
