Custom Kickstart boot screen?

Amiga1992 · 19 December 2011, 13:20

I searched around for this but haven't foumd anything.

Is it possible to change the Kickstart boot screen at all? The classic "insert disk" animation.

I was wondering if making a custom rom would work out.

If u are a coder maybe u could use the opensource AROS kickstart amd modify that?

I'm a retard, not a coder

If I remember right, the K1.3 image was stored as code rather than as a bitmap you can easily replace. Is this possible? Newer kickstarts have the animatoin which I suppose is more complex.

I thought it must have been some trick like this when I first read your question, otherwise it surely would've been done, after all, who hasn't replaced the windows splash screen with a kickstart . . . tumbleweed . . . .oh just me then

Sounds like a fun challenge for a coder, find the ROM code for the kickstart image, make it do something different in a softkicked version, a micro demo . . .

EDIT:seems like there were mixed views on whether this would be lame or cool a few years back -

Leonardo Fei's Virus Guardian patched the Kickstart picture to have it modified on a reset.

I believe there is a more flexible way to solve this:

Instead of creating a custom handcoded bootfloppy animation replacement, it would be better to have a Blizzkick/Remus patch that simply patches the former boot animation code, and insteads loads an anim file, with a specific name and format from rom. So that anyone could potentially customize its modded kickstart to his/her liking, just by adding that patch and the anim file that fits that special format.

I bet we have lots of talented asm coders over here, and one of them could probably take a challenge on this task.

So, if you are reading this, and have the skills I invite you to test them on this project

The animated insert floppy disk screen is only displayed if a boot-able volume cannot be found. So us hard drive users seldom ever see this screen. Another issue to be considered is physical ROM space limitations which are now being crowded with the BB2-BB4 updates (even without Cosmos' graphics.library). I suppose if you can keep the code size reasonably close to the original it might work out OK but is it really worth the effort?

am sure thers a few patches to do this on aminet, but who watches Kickstart boot screen ???

If you have an Indivision, it displays a boot screen anyway. so there must be a way to modify th ROM to display a screen nonetheless, for X ammount of milliseconds.

hummm can`t seem to find anything on aminet but I`ve deffentaly done something like this back in the day

Have your routine show up as a rom module (romtag in front). Then you can have the machine for a moment before the insert disk screen as Exec initializes the various modules.

AFAIK Indivision's boot screen has nothing to do with the Amiga. I think it's just a bootscreen coming from the FPGA that displays once Indy gets powered.

Correct, so even if your amiga is screwed, but still supplying power, you get an output.

Jope · 21 December 2011, 20:24

Yep, the Indivision is special in this sense, but it reminded me of an old German HD controller for the A500 that had a splash screen on bootup as it scanned the SCSI bus.

This made me think of the romtag approach.

I'm guessing it was done the same way as the AR splash screen?

Jope · 26 December 2011, 12:54

The AR is a bit special, it hijacks the machine in a ruthless fashion.. Toni once explained it to me, but I don't remember all the details now.
