SuperKickstart-Disk?

[Kitty]

SuperKickstart-Disk v2.0 rev 36.143 (1990)(Commodore)(A3000)

Can someone tell me what the differences are between this and a regular version?

For what do you need it, if I may ask?

I was looking through a list of Kickstart roms (I legally own ehem) I was just playing with the minimig changing Kickstarts,
compairing game differences, nothing too exciting
Strange though they are only 1 disk versions I have (says 3 below) also they are adf and not actual rom files, are these like the Amiga 1000 where you have to boot kickstart via floppy? A1000 ROM Bootstrap (1985)(Commodore)[u].rom

Commodore
1990

Amiga 3000 (only the first models)

36.68
256KB

3 disks
Super Kickstart
Workbench 2.0
Extras 2.0 Tools 2.0

The first version of the "new" hardware-based Workbench side on a Kickstart 1.3 ROM. Just as it was known from the Amiga 1000, Kickstart has been loaded from the floppy disk 2.0 "Super Kick Start". Only then could start the Workbench 2.0.

Okay, hope it helped then

Superkickstart disks are used on A3000 with KS1.4 bootroms.

If you have KS1.4 fitted the A3000 loads files (either from floppy disk or hard drive) into RAM and uses the onboard MMU to MAPROM it.

or my old 500 when we wanted to see what the new wb2 looked like, crumbs that was a few years ago

I really doubt you used a superkickstart disk on your a500.. Skick, zkick, etc I can believe.. Or even the GMBH c00000 2.0 self-booter.. :-)

[cosmicfrog]

well probably your right there not the superkickstart disk

probably skick like you say

[Shadowfire]

alexh is correct.
The first A3000's were designed / shipped before 2.0 was finished. The engineers knew that the ROM was going to be different than what they had, so they bolted on an A1000-style kickstart loading system; the system shipped with a "1.4" ROM, which would look for a file called "devs:kickstart"; or, if it couldn't find that, it prompted for a "Superkickstart" disk. The difference between an A1000 and A3000 kickstart disk is as follows: Superkickstart contains both 1.3 and 2.0 images. Superkickstart also includes "bonus" code for the A3000's hard disk controller. The built-in 1.4 ROM would load in the kickstart image and set the MMU (all A3000's came with an MMU & FPU) to map it at the usual memory location.
Later revisions had a 2.04 ROM instead of the 1.4 ROM. If you hold down both mouse buttons on powerup, and the machine pulls up a "Kickstart menu" with 4 buttons, the machine is 1.4. The 1.4ROM (if you exit out of the superkickstart selection screen by clicking on the hidden "close window" gadge) uses a blue/white/orange color scheme by defaul.

I guess the gist of all this is, you don't need to be concerned with the Superkickstart disks. Use the regular ROM images for UAE (depending on OS). Minimig emulates an A500 so use one of those images.

Where can I find an image of the A3000 or A1000 boot ROM ? I would like to study it to have the same principle for the MCC or any future FPGA based accelerator (i.e. loading any Kickstart from the built-in SD-Card).

[cosmicfrog]

I`d search torrent sites Frederic or ask someone to email it to you

now I`m going to be quite incase I get slaped hands

its a shame we can`t link or post stuff like that but rules are rules, there to help keep us all happy

The A1000 boot rom just reads the kickstart into the correct place in RAM, then it does a certain write to an address and some logic makes the RAM write only from that moment on.

The A3000 1.4 ROM loads the kickstart into FAST ram and then maps those pages to the normal F80000 address using the 030's MMU.

Don't know how relevant either of these are really, if you're designing some future product, then you can just make the logic and firmware for this yourself.
