Amiga OS 3.1 vs 3.5 vs 3.9 system difference
2020年10月14日 · AmigaOS 3.5 and 3.9 still rely on the Amiga Kickstart 3.1 ROMs which is where most of the code lives that handles the bits you're asking about (memory management, etc). The OS could have included patches to the ROM, but I am not aware of anything significant (certainly no virtual memory support).
Protected/virtual memory support in classic AmigaOS
The Classic AmigaOS had a very good reason for not implementing protected memory when newer 68k CPUs with embedded MMUs became commonplace. The main reason was the pervasive use of shared memory message passing to communicate between tasks, including user tasks, system tasks, and device drivers.
AmigaOS 3.9 - where can I buy it?
2023年9月25日 · Workbench 3.2.2 means you have AmigaOS 3.2.2, which is about 20 years newer than AmigaOS 3.9, so you'd be going a long way backwards. 3.2.2 will have no trouble with a 68060 and lots of RAM. (And yes, the version numbering is confusing - there's about four branches of AmigaOS development post-Commodore) –
amiga - What's the most recent version of AmigaOS?
2023年9月24日 · At this point, AmigaOS 3.1 was aging poorly - it had trouble with hard drives (emulated hard drives, in the case of Amiga Forever) larger than 4GB, and other bugs were affecting it. Cloanto could not develop AmigaOS themselves, but they took the 3.1 ROM and applied some bugfixes and updates to it and in 1999 started their version of the ROM ...
How hard would it be to port Amiga OS4 to x86 or ARM?
2017年9月30日 · AmigaOS 4 only runs on PowerPC CPUs, but was largely based on AmigaOS 3.1 source code which only ran on 68k CPUs. So the code base has already been ported from one architecture to another. The difficulties in porting would probably come from endian issues and the almost complete lack of any Amiga-compatible hardware devices on any existing ...
How does stack size affect functioning of AmigaOS and programs?
When former programs run out of their current stack, new virtual memory page is allocated by OS (or the program is artificially killed once it past stack limit). For amiga, nobody checks that (AmigaOS is not using benefits of virtual memory) and the programs just ends up using non-allocated memory, corrupting other programs memory, OS, etc. –
amiga - Is there a seamless, Wine-like AmigaOS emulator for Linux ...
2020年11月15日 · AmigaOS has stdin and stdout just like Linux has. What I am after here is an Amiga emulator that maps the AmigaOS stdin and stdout to Linux stdin and stdout, not to the Amiga graphics chips. The entire system would not have to …

Creating a new locale.library language support for AmigaOS
2017年8月14日 · Looking at Amiga localization in general might also be helpful, see the Locale Library page on AmigaOS. Of course, these pages focus on AmigaOS 4.0 and up. And then there was the Amiga Translators Organization. A gathering of people on the net involved in (voluntary or professional) translation of Amiga product.
What tricks or techniques were used to speed up AmigaOS boot
2020年11月3日 · In general, booting an Amiga from an HDD is quite fast, and can certainly be far less than 30 seconds even when a significant number of drivers and small applications are loaded via commands in S:Startup-Sequence.
