winuae.zip updated yet again. Sarge's installer now runs (until it asks for non-existing CD..)
I guess Gayle IDE ATAPI CDROM emulation is needed next... (at least it is simpler than SCSI adapter emulation) |

Yeah, I've seen the installer running. I think the progress is simply incredible.

btw, you can press ALT+function key to open another console when installer is open and play with basic shell commands/look for /proc entries without need for real installation. Pointless and useless but so is running Linux on emulated Amiga Remember that there is no: - CDROM hardware emulation (except CD32/CDTV but I don't think Linux supports those..) - Ethernet (uaenet is AmigaOS driver) - Graphics card (Picasso96 is AmigaOS driver, only framebuffer is hardware emulated) |

Rather than SCSI CD-ROM drive emulation, is there any possibility to "own" a real SCSI device connected to the PC's SCSI controller? In other words, all commands sent by the emulated Amiga are passed straight through to the drive and Windows wouldn't send any commands to the drive itself since WinUAE owns it. |

Toni I just tested a little more today.
Looks like MMU is working in the WHDLoad context but with 2 bugs: 1) when there's an access fault, the PC is after the faulty instruction. On a real amiga, the PC is on the instruction (so resuming execution triggers access fault again) 2) I was able to use it only when I start with MMU on. If I enable it after having booted, it is not active. Maybe something to do with 68040.library at startup? Anyway, this is not very convenient at the time being but looks very promising!!! thanks |

EDIT: AFAIK 68040 can even delay write faults (writes are async), PC may not always point to immediately next instruction.. ("write" = instruction that does "normal" single write at the end, this does not include special cases like MOVEM to memory) What was the exact instruction? Quote:

my 68040 test machine is now configured, will next add full 68040 mmu support (Snoop/Protect) and afterwards test it with WinUAE

Wouldn't that be a dream if finding whdload access faults with WinUAE was possible?

Finally found a way to install without that unsatisfied demand for a CDROM. Just use the initrd22.gz from hd-media folder (Sarge) as initial ramdisk. Now the installation hangs at the network adapter, so I will describe the problem in the appropriate thread.

I am not sure this will help much, but CheckMMU reports no cookie.
With a 040, SET040 is needed in the path to run it. After installing I simply typed
Oh, I am lamulating in case you hadn't notice yet . To answer Kyon's question, the MMU is also used by WHDload. So you might want to enable it. Check that your game icon doesn't have the nommu set, if that's the case put it into (). In WHDload prefs, remove the ; in front of MMU and you're done. This is especially useful with the latest WinUAE betas, in which the emulation is more accurate, and a missing MMU is reported as an error by the slave (missing in the meaning : unticked in WinUAE). |

Hey guys, did the development and testing of the MMU-support stop here? Seems like some people lost interest... But surely, MMU-support could lead to some cool stuff?
So... anything new to report? |

MMU emulation works except there is some unknown corner case that is practically impossible to debug using current method (in Linux some user space programs crash randomly)
I don't really care about MMU in emulation, for me it was yet another interesting learning experience (how exactly 68040 MMU works etc..) |

Btw, did anybody succeed in installing NetBSD yet? You need a disk partitioning tool, which I don't have, for that. It's probably not hard with WB 2.0 or newer.

Possible good news: I was cleaning up MMU code (put back C++ exception handler now that WinUAE compiles as C++) and decided to disable some MMU table caching in MMU code (speed optimization)
NetBSD MMU error crash disappeared. It seems cache gets out of sync in some situations ("slow" MMU table routines return "access ok" but cache says "nothing mapped here") http://www.winuae.net/files/b/winuae.zip I'll contact Aranym developers if I can't find any obvious reasons for this error (perhaps it is some Atari-specific assumption somewhere that simply won't work with Amiga or something..) Hopefully it is now possible to create installed netbsd or linux hardfile |

Heh, cool. Good work. I'm sure some nutters on here will be trying it as I type.
