Idea: Compact Flash-based kickstart (and thus HDD) replacement?

[Gulliver]

I have been waiting for a 1 MB flash rom solution for over two years. But despite there are a lot of people interested, none of the usual hardware sellers seem to think this kind of device would be comercially viable, for some unknown reason.
I know there is the kickflash and the eflash4000, and even the deneb card, but then A1200 and other non zorro Amigas are left in the darkness .
Having to buy an eprom burner with adapters and having to deal with many difficulties to acomplish a similar goal is not really good. I am all for a comercial solution for this.

It has already been done. But no one has yet provided a comercial solution for non zorro Amigas that involves a flash rom.

My friend Gulliver,

You mean something like Doobrey's A1200 Flashrom prototype?

I wish something like this would be made as a commercial solution.

@mfilos

Indeed my friend, something like that would be really great

Why not just soft kick if you already have a CF ide with your own custom rom file?

Set it up like this:

Turn Amiga on with a floppy in the drive (game or demo) it is going to use the ROM on the motherboard and boot the floppy as expected.  (My case 3.1 is the physical rom)  Most likely if your booting from floppy you won't wan't a 3.9.x custom hack for compatibility reasons.

If no floppy it will boot from the HD.  First thing it does transparently is soft boot your 3.9.x rom, reset and your then you're off and going.  If booting from the HD it just loads the HD.

So let's say you want to boot from USB.  Plug the USB device in the USB port and even at power on it will softkick/reset/ and start booting your USB drive transparently.

I'd also have a script that when booting from the HD if you hold a key down it will bring up a menu that lets you choose any version of the ROM to softkick.  1.x -> 2.x -> 3.x


Best of every possible world.    No custom hardware needed at all.

It is not the best really. You will notice a big boot delay if you do that, and then if you dont have a MMU to protect the memory space where the kickstart is, some program, most likely a patch will probably corrupt that memory area, and guru your Amiga. Another drawback, especially for low end sistems is that you will loose as much memory as your rom occupies (512KB, 1MB or 2MB depending on this new kickstart size). If your disk gets screwed someway, bye bye kickstart.
So there are a lot of disadvantages, and much more that I dont remeber right now.

False.
3.9 already does this and it so fast it is almost undetectable when booting from CF.



False.
Just about everybody that uses 3.9 IS softkicking (except the 3 people that have burned their own 3.9 rom).  So this seems very unlikely.




True, but we are talking about people wanting to use a 3.9 kickstart.  If you are using 3.9 you have a ram expansion.



Again this is ridiculous.  First of all the kickstart ROM will always be on the motherboard.  If your harddrive crashed I think the last thing you would worry about would be a kickstart image file.  


This whole posts sounds like you are posting fud.

I am sorry if you felt it that way, but it was not apersonal attack on you, it is based on facts:
Loading only a few modules like the AmigaOS ROm Update does, it is not the same as softkicking an entire kickstart. And having a rom with all the updates you want is much faster than loading them from disk anytime. Try it.

And again if your harddrive fails for some reason, you will end up with your old kickstart, with all the bugs and unsuported features it has, just to name a few examples: no >4GB disk access and no USB support, etc. So for example, if you relied on USB to boot with mouse and keyboard, then you simply will have to buy an Amiga mouse and proper Amiga keyboard, because your USB ones, wont work.

And not everyone that uses 3.9, softkicks. Many arent able to use Rom Updates at all.

I agree, it should be probably simpler to split both functions.
