#workbench2.0-amiga1000?
3 messages in this thread
Dege,
Thanks for the education, I didn't know that. I thought I had once read
that the A1000 had only 256k of memory space allocated for the O.S. which
prevented the larger 2.x O.S. from being able to be loaded? I don't know
anything about zkick or how it works. I am happy with my decision to put the
DKB kwickstart ROM switcher in my A1000. It has worked well for me and is now
being borrowed by my brother (I can't seem to let it go though, besides the
sentimental attachment I'm sure it will be a collectors item someday).

PMFJI. The A1000 had 512k of RAM, and 1/2 of that was for the writable control
store (WCS) that held the Kickstart information in it. If was desgned to be
protected so that when you rebooted, Kickstart was still in RAM. Kickstart 2.x
is a double sized ROM (512k) compared to 1.x and the WCS can only accomodate
256k for Kickstart. In that respect, you couldn't use a 2.x OS on a stock
Amiga 1000.
Kwikstart II does the job, letting you switch between ROMS. ZKick et al set
aside an area of RAM to store the Kickstart 2.x image so you could use it on an
A1000 or others of the family without having to upgrade the ROM chip.

Christian,
Thanks for the info, I knew the longer I hung around here the more I would
learn. BTW where can I find ZKick? Is it PD, Shareware or commercial? There
is one game I own that does not operate properly under 1.3 or 2.1. I would
like to use ZKick to load 1.2 O.S. to play this game for old times sake from
time to time.
