What's the difference between 3.0 and 3.1 amiga roms?

[RobA1200]

Or more exactly what are the bug fixes or more interesting features? Just wondered?

39.106 to 40.063?

Thanks!

The main difference between those two ROMs versions is the ability to install larger hard drives (> 4GB) through the scsi.device which you cannot load it with 3.0 ROMs.

On the other hand, various bug fixes introduced since the previous version, support for CD32's custom chip Akiko (chunky2planar) and the introduction of 2 new datatypes: ANIM and CDXL in Devs directory.

Although you can install Workbench 3.1 under 3.0 ROMs, it's not completely recommended, as it might look and load ok, but there is the probability that your Amiga will not be stable due to some library functions executed.

Another "interesting" "feature" of the 3.1 KS is that it'll disable PCMCIA if it detects RAM present in the 6-10 MB range, supposedly to avoid conflicts with PCMCIA RAM cards. This will of course take down any PCMCIA card, not just the RAM ones.
KS 3.0 doesn't have this problem, so non-RAM PCMCIA cards which map their I/O to other segments of the memory map can happily be used with 8 MB RAM cards/accelerators that use the 6-10 MB range.

But there are patches to fix this issue!

Only if it maps into the 24-bit range, which is generally plain Fast RAM boards, 020 boards and cheaper 030 boards.

You are both correct.

The address range for the PCMCIA port is 0x00600000 to 0x009FFFFF, the 6-10MB range in the 24-bit (and technically the 32-bit) address range. This range is also allocated to the 'top' 4MB of FastRAM in the 24-bit range.

Nice list.
