Hypothetical Kickstart ideas

[save2600]

I don't get it. What's the game got to do with Kickstart?

[little]

If I remember correctly Dragon's Lair for the Amiga 1000 had it's own kickstart as a mean to save precious ram.

[save2600]

Well I'll be dipped. That sounds really cool, but awfully strange. What does it do... re-write Kickstart with a very streamlined one that doesn't use as many resources? This would mean it patches Kickstart, right? Erasing what is there and replacing it. If so, how come no reset? Game seems to simply fly off floppies. Figured they had their own proprietary crunching/de-crunching scheme, but not a Kickstart hack.

Twinkick "3.9"
KickWork3.1
KickTOS

1. You could use a ROM switcher to change kickstart versions, and create your own if you wanted.

2. You can sotboot a kickstart image such as with softboot, blizkick, etc.

3. You can patch/change system library code during boot.

4. AmigaOne has kickstart on hard drive. I assume SAM does as well. OS4 classic certainly does not come with a ROM chip...

@Ratte:

KickTos... now we're talking  :-)  How does one get a hold of that brilliant piece of coolness? Twinkick I'm familiar with, but Kickwork3.1... what was that all about? Or should I fire up the German translation program?  lol

@save2600

Rembeber that the amiga 1000 (as well as early 3000s) loaded the kickstart into ram, they did not had roms built in the motherboard.

[Ratte]

Kickwork is a complete 512KB 3.1ROM crunched with LZMA down under the 256KB WOM limit.
The 256KB includes the crunched rom and some decrunching code.
The Kickstart itself is modified with an enhanced version of Pirus Kickwork-Patch.

... Its a Kick3.1 + WB3.1 on one disk for the A1000 ...

@billt:

I'm aware of the first three suggestions, but have no experience (yet) with the other machines and OS4.x

@little:

Thanks, yes I knew that :-)

@Ratte:

Didn't know Piru had an all in one solution. Guess I'll hound him for a copy  :-)  I've been using Andre's Twinkick, which is brilliant. BUT... on a 2.5mb A1000, you lose 256k (boo-hoo).  lol  

If I am reading this right, with 3.1 squished to fit into 256k, I should have even more ram  :pint:

Unpacked it will still be 512k :-)

[save2600]

Oh - and duh. He did that in able to fit the whole bloody lot into an 880kb disk I suppose.  :crazy:   But perhaps a routine was written to throw the extra 256k in Fast Ram then?  And I'm sure that's got to be within a certain memory confine (my autoconfig expansion ram). Which since TwinKick works, Piru's should still work  :-)

details about kickwork

the crunched 256kb are loaded to the wom
decrunching a 512kb (executable) rom-image to fastmem
same as twinkick, but without kick1.3
but it is able to repair the romimage in fastmem if some kind of code or a systemcrash destroys the rom
the "kickwork"-patch is added for fun only and has nothing to do with the lzma-compressed kick3.1

save2600:
did you read your complete emails?

@ratte:
a little OT, but have you noticed this thread:
http://www.amiga.org/forums/showthread.php?t=41497
maybe u could help them out with the aros kickstart replacement project? docs like the kernel reference manual are needed.

>amigaksi, I know my update-I/O suggestion have serious drawbacks. But so has other approaches to. The only really clean path is FPGA

FPGA, you mean "Forget Programming to Get an Atari"?   I thought it was "Forget Programming to Get an Amiga" since Atari ST was more emulatable.

>VBI is however a suitable opportunity to update at.

For joystick i/o, Atari st uses 7812.5bps instead of 50/60hz.

Another useful item for A1000 users would be to compress the 256K kickstart into the bootstrap ROM space and decompress that into the WOM upon power-up.  Using a pair of 27512 EPROMs to replace the bootstrap ROMs would give you 128KB so compress the 256K Kickstart into less than 128KB (and decompressor also would have to fit into that space).

Perhaps, someone who has the copyrights to those bootstrap ROMs and Kickstarts could do it.

its easier to add an rom-socket to the a1000
