How to get AROS m68k to run?
« on: April 19, 2011, 02:35:35 AM »
I tried AROS m68k in e-uae-0.8.29.w4_5 and uae-0.8.29_1 and it will only show a black screen with 2M chip + 1M fast. In all combinations of 68000/68060, ECS, AGA, A500, A1200 etc.. While both kickstart 1.3 (512k) and 3.5 (512k) works without any problems.

So what to do, to get AROS-m68k running?

Kickstart 1.3 should only be 256k.... and did you try inserting a Workbench disc?  :lol:

I tried a KS1.3 from some site. Anyway it should show the "insert disc" image without a disc.

AROS 68k has two ROM files, a Kickstart and a Kickstart ext, you will need both (i forget the e-UAE options to load that). The emulator should be set up exactly as an A1200 with 4meg fast ram and if possible RTG. It should work then, IIRC AROS doesn't show a disk prompt you should ensure a bootable disk (hard or floppy) is available)


Note: re the 512k 1.3 ROM, I had to double up my ROM image to make DOS UAE work many years ago... I guess any that are floating around probably still are doubled up :)

68k AROS only works on actual Amigas and Winuae at the moment. Even Winuae needs to be at least 2.3.1b8 (although Id suggest using actual 2.3.1). None of the other UAE's are upto date enough to run it.

Near as I can tell this is where I write something under the guise of being innocuous, but really its a pot shot at another persons/peoples choice of Amiga based systems. Unfortunately only I cant see how transparent and petty it makes me look.

fishy_fiz, What is the magical difference in the WinUAE update that makes it work?

(or what makes the current ROM so troublesome?)

Seems the emulator (uae) get's stuck at this:
F812A0 MOVE.W $00DFF018,D0
F812A6 BTST.L #$000D,D0
F812AA BEQ.B #$FFFFFFF4 == 00F812A0 (TRUE)
F812A0 MOVE.W $00DFF018,D0
etc..

What's at $00DFF018 ?, SERDATR ?

I checked the kickstart 1.3 file. And it's duplicated 2x. :)

As for the AROS-68k it consists of two files rom + ext. And the emulator only loads one. So I assumed it has to be loaded in one contiguous file. Ie "cat rom.bin ext.bin > emu.rom".

Seems $00DFF018 really is SERDATR and thus it waits for the serial receive buffer to become 0xD .. doh..

The UAE debugger also misses intuitive help text ...gah

If I put NOP (0x4E71) into fileposition 0x12AA (F812AA) then uae at least starts to show lightgrey. So it's not completly fucked ;)

While it won't work in EUAE, if you did find a combination that worked, the most likely ones would require graphics card emulation.  It is that way because the AGA-specific drivers don't work very well since they are incomplete.  Currently Toni Wilen, the WinUAE author and Kickstart bounty #2 programmer, is working on implementing automatic screen switching for the chipset modes and RTG modes to share a window.

I was wondering how to get this running on an actual Amiga.  Anyone have a breakdown or a web link that explains it step by step?

All this hullabaloo surrounding legacy OS is starting to frustrate me :)

TheBilgeRat:
download the current nightly. in the distfiles folder you will find an adf archive of a boot floppy. using f.i diskimage device (http://aminet.net/disk/misc/diskimage.m68k-aos.zip)
you will be able to decompress it to a real floppy. also the best is to prepare aros boot partition on a hard disk (just coppy the content of nightly to it and mark the partition as bootable).

now, boot from the prepared floppy drive, which will extract the aros kickstart to ram and boot from there. you can recognize aros kickstart booting by dirty-ocker-yellow color on screen (lol). if you have a bootable aros harddisk partition attached to the system (preferably via internal ide or accelerator scsi) chances are that your system will boot to wanderer. be sure to have it a highest priority hd.
i have tested and can confirm a4k 030/040/060 as working, except for csppc. also many configs of a1200 work, in particular blizzard 1260. there is problem wit elbox fastata so far i see.

anyways further testers would be very welcome.

i suspect aros might currently boot up on a1200 with 4mb fast ram. i will try to test it tomorrow since i have an exemplar in my studio. it should through definitely boot from ide on a1200/a4000 equipped with =>030 and 16mb ram. note that aros is still generally very slow, especially on aga.
