Minimum requirements for AmigaOS 4

[freqmax]

What's the minimum requirements for AmigaOS 4 in terms of chip and fast memory, graphics chipset, CPU, speed ..?
How much ROM/EEPROM does AmigaOS 4 machines need?

[freqmax]

128MB RAM (Fast RAM - you only need chip RAM if you wanna use the classic chipset)

Significantly more than the 4 MB requirement for AmigaOS 3.

Seems the culture of keeping things slim went out of the window.

ROM / EEPROM? Not necessary. Kickstart is loaded into RAM from the hard drive during boot.

I have still to find the CPU that will load anything from any disc storage by itself. Ie, all computers have some kind of startup "ROM". The only thing close is some ARM CPUs that has a circa 2 kB builtin ROM that will serially download code from I2S based EEPROM.

The minimum requirements gives a good hint on how much an OS wastes in internal management.

CPU: 160 MHz PowerPC 603e
RAM: 64 MB
GFX: ECS
HDD: 1000 MB

Does AmigaOS4 support OCS?,
1 MHz PPC is not likely to exist
How much ROM (BIOS) is needed to load the AmigaOS4 ?
Is GUID partition table supported?

but most of the memory footprint is pretty legitimate, and it can be reduced by stripping out modules if you're that way inclined. For example, the Kickstart supports a much broader range of hardware, including graphics cards and USB, and so has greatly outgrown the original 512KB ROM.

Graphics, USB, CDrom, etc.. Can be handled like dynamic modules so that it won't hog the memory. If one care for optimal resource usage.

My idea is that when device X (like a CD-rom) is used it will be loaded dynamicly. When it's not used for a while it will be flushed and so on.

@Daedalus, Easy, load the driver, probe, save result. As for USB load the USB bus driver but treat other sub-drivers like the first one.

Just because there are resources isn't a good reason to waste them. One example is embedded usage where less resources saves equipment and battery etc..

[freqmax]

Kind of, anyway this kind of optimization is possible. And bloat is just the sign of sloppy programming.

FreeBSD does more, and can boot within 32 MB using X11. I have even booted it with 4 MB provided there's lot's of swap.

Just shows that 100 MB is bloat..
