support for AROS boot rom
I suppose the AROS rom support deserves its own thread.
Both booting WinFellow with the AROS rom and with the ADF images results in a near black screen. Serial debugging must be enabled at compile time. ![]() Who can supply me an AROS rom or ADF image which is compiled with the keyword AROS_SERIAL_DEBUG defined? ![]() |

All official AROS m68k-amiga builds have serial debugging enabled.

Great!
I'll check the AROS source code on which data to expect and were it would land in the Amiga registers. |

The serial port is not emulated by WinFellow...
![]() The near black screen is the result of an endless loop when waiting for the serial port transmit buffer to become empty. ![]() Let's see how much work it is to get this serial port emulation going. ![]() |

After setting bit 13 (transmit buffer empty) of register SERDATR to 1, WinFellow is able to boot the AROS ADF-image. This results in attached screenshot.
I had no luck booting the AROS rom-image. It keeps on resetting for some reason. Is there interest in releasing a WinFellow snapshot which allows booting the AROS ADF-image? |

![]() Also if being able to boot the AROS adf image would be the only improvement? |

Thanks, Worfje!
![]() It's great to see the 'WinUAE alternative' back in development, even in some small way. ![]() |

A dropped a candidate for the snapshot in the private WinFellow beta release thread. Not much beta testers left after having a 5-year break in releasing snapshots.

Awesome work! I'd be interested in trying any new WinFellow snapshot(s).
Perhaps the MESS team may also find AROS ROM useful for their Amiga emulation. |

I would like the AROS rom to work with WinFellow, but WinFellow does not yet support extended ROMs (like applied in CDTV and CD32).
From Toni I understood that booting the first AROS rom (so only the first 512Kb) should already show something usefull, but with the latest snapshot of WinFellow it keeps rebooting or results in a purple screen (depending on selecting 68000 or 68020). Next to this, it seems that the rom only supports trackdisk loading. This was stated here. So, I could use some help on the status of the AROS rom and how it should respond when only using the first 512Kb of the two ROM's. |

I meant lots of debugging stuff will be written to serial port before it crashes or hangs. I recommend writing all bytes written to SERDAT to a file. Serial log makes debugging much easier.
Nothing will appear on screen because graphics.library and intuition.library is in extended ROM ![]() Most autoconfig hardware is supported, including bootable harddrive controllers, that page is totally obsolete. |

Toni, that makes it clear to me.
I already had a glance on how much work it would be to add extended ROM support to WinFellow, but I am not yet sure how much work it would be. |
