Romy A4000 & A3000

I'd love a Kickstart that would have PFS3 native for large HDs, CD ROM support native, etc.

You can/should store PFS3 into your Rigid Disk Block (RDB) of your hard drive that way it is available the instant you turn on your computer.  Commodore did a lot of things right and that was one of them!

Can anyone make a list of things that are useful to add into this new 1MB ROM?

Like what are all the things needed to 100% overcome the 4GB HD limit?

Someone should make a selection of custom ROMs for different machines.

As far as A1200s go, the perfect ultimate 1MB ROM depends on which accelerator you are using.

There are certain things that every machine needs added into the ROM.
But there are other things that are specific to certain hardware configs.

I'd like a ROM: drive so you can boot into a minimal WB without any disks. and all the basic CLI commands.

When optimized versions of the commands are used, all the standard CLI commands are very tiny.

So it seems reasonable to have a standard AmigaDOS cli command set be RESIDENT inside the 1MB ROM, assuming you don't use the extra 1MB for all sorts of fancy libraries, or MUI or something.
