Has anyone tried to run Minix under Ibem? I would expect that Minix would need to be recompiled with different console code and floppy access code, but does Ibem emulated the rest of the PC hardware (timers, dma, etc).

IBeM will not run Minix. Minix (as far as I understand it) ignores the BIOS completely and accesses the hardware directly for everything. At present, IBeM only emulates a small amount of hardware, eg the screen and keyboard. The disk access *must* be done through the BIOS, and apart from the timer tick, there is no timer/DMA support.` One of the questions I'd ask is why? Surely Minix exists for the Amiga now, doesn't it? - Mark Tomlinson

On the subject of Minix, how's the latest version of Minix for the Amiga run? I know older versions do not have hard drive support and won't work on an Amiga 3000, but I got the file "aminix.lzh" off ab20 last week and it looks like it supports hard drive usage. I suspect that I would also need the full version of Minix in addition to what comes with this archive. Is anyone running the latest version of Minix for the Amiga off hard drive? What I really want to know is 1) does it really work off hard drive, and 2) will it run on an Amiga 3000? It appears that it may be some time before Commodore offers their Unix package separately, but if I could at least run Minix on my A3000 off hard drive, that would be pretty nice. -- Rick Kent // Only California State University, Bakersfield \X/ Amiga!

It might work; but I doubt it. I am not particularly familiar with Minix, but
first of all, IBeM only emulates an XT (8088). Doesn't Minix require at the very
minimum a 286?
Also, on a 25 mHz A3000, IBeM runs about 0.5 to 0.7 times as fast as a
4.77 mHz 8088. This is damn slow, and I think that Minix would crawl under
it even if it did work. I mean, like fifteen minutes to log in!

However since it was literally, just, released the origional poster was probably fed up with the fact that 1.5.10.0 did not work to any reasonable extent. The guys who did the work for 1.5.10.1 have done well to get a working version, and should be thanked for all their hard work. Now 1.5.10.1 is out all I want to do is to run PC-MINIX on my bridgeboard and implement some sort of multi-processing! ***************************************************************************** * Stuart Millington * "A Mind Is A Terrible Thing, Remember * * UUCP:...!mcsun!ukc!warwick!phupp * That." - David Bryan, Bon Jovi * * JANET:phupp@uk.ac.warwick.cu ***************************************** * ? :phupp%warwick.ac.uk@nsfnet-relay.ac.uk <- E-Mail moving soon * ***************************************************************************** E-MAIL is now at uad1146@dircon.UUCP uad1146@uk.ac.dircon

I suspect that I I don't think that the version on ab20 is the most recent one, I recommend that you only look on ftp.cs.vu.nl for updates (directory /pub/sreiz/minix), that way you are sure to always have the latest & gratest (ahem) version. The new version does indeed support harddisks and a3000s, we've debugged it on two a3000s and it works very nicely. >would also need the full version of Minix in addition to what comes with That's right. Alternatively, you can first try out the demo version, to see for yourself that it works with your harddisk and your cpu. The demo can also be found on ftp.cs.vu.nl. >this archive.

This is probably a dumb question, but what is Minix and Aminix? I read all the Readme and Contents files about it on ftp.cs.vu.nl, but all I can gather is that it makes my amiga act like a text only unix.

Commercial, Prentice Hall price is $169, comes with full source. Updates are available via FTP.

Surely Minix exists for the Amiga > now, doesn't it? I don't want to lose the advantage of an advance OS on the Amiga. I want to keep running the Amiga's OS. If I was never going to use my Amiga as an Amiga then sure, I could boot Minix. But I'd rather have both system's at once. I'm not considering running Minix unmodified. In article from "Charles Cazabon (186-003-526" <cazabon@hercules>: > It might work; but I doubt it. I am not particularly familiar with > Minix, but first of all, IBeM only emulates an XT (8088). Doesn't Minix > require at the very minimum a 286? Minix only need an XT compatible to run, but there are versions that need specific modes only the 286 or the 386 and higher can support. Thing about this a bit and the port looks even easier. Assuming that IBeM implements BIOS in the 68000 environment (it should be for speed) then the various low-level functions of the Minix kernel could be implemented by BIOS calls. The main reason this isn't already done on the PC is the BIOS calls are not reenterant, but the BIOS calls on IBeM are atomic getting rid of this problem. The only problem this leaves is can occasional timer interrupt. This seems to be the only point of difficulty as DMA can done with direct program I/O if necessary.
