A1200 - Blizzard 1230 Mk4 and BlizKick

[NovaCoder]

Can someone explain to me how this all works.  If I set the jumper on the card to copy kickstart into from chipram to the card's RAM does this actually do anything on it's own?  I did try copying a copy of my ROM file (using GrabKick) into my DEVS/Libs (running on OS3.1 using AmigaSys) and the Amiga just got stuck in and endless loop and wouldn't boot to WB?

Do you also have to install the BlizKick software?  What's the diff between the BlizKick software and just setting the jumper?

And finally, I'm assuming that chipram usage goes down if you succesfully copy the ROM to card memory?

Thanx  :-D

 F. E. : You want to patch some original ROM instruction before the Amiga boots. Then you simply to add BlizKick to your startup-sequence with the path module stated.

 Presto! After a second boot (did from the BlizKick itself), the patch module will be available to the system.

So if you just want to run with your ROM, you just have to set the jumper on the card to automatically copy your image to fast ram?

Do you have more available chip ram after this jumper is enabled?

The jumper maps the ROM into fastram, otherwise data is read from the ROM directly (no chipram used).

--edit-- Actually, a few parts of the ROM still do end up in chipram (expansion and exec IIRC), but those can also be moved to fastram.

 

Very interesting, thanks.
