The Kickstart disk on the A1000 is the equivalent of the ROM.
It doesn't load into normal memory, it loads into 256K of
private memory that is then write protected and appears to the
system as ROM.
The patch feature is the "ROM tags in RAM" that was introduced with
KS 1.2. The system uses that feature to determine if you want to
use a ROM routine or your own. I believe Andy Finkel used that
for the SETALERT fix because the ROM SetAlert routine had problems on
systems that had RAM located at C0000000, like the A2000 and 1Meg
A500s.

| 1802.2 | KS -> ROM? | WJG::GUINEAU | Somewhere else in time | Fri Oct 21 1988 12:03 | 4 |
| I had a (for CBM) rather un-nerving thought. Could I (and some clever hacking)
take the KS 1.3 disk in my upgrade "kit" and blast a ROM?

| Well, how 'bout a NoKlickStart for the 2000 to eliminate drive klicking?

| re:.2
It was just mentioned on usenet that there is a program that will
read the KS and output the contents in the right format for an
EPROM burner. I believe it said you would need four EPROMs
(costing about $10 each). Given that CBM is selling the real thing
for $45....

p.s. Is anybody doing a daughter board for the ROM socket, so that
a toggle switch will let you switch between ROMs? Given the number
of changes to the ROM planned for 1.4, it might be nice to be able
to run the KS 1.2 for badly programmed applications.
