I think you have to let take a look at your system.

I always have MapROM turned on, and whenever I run a program that is
very bad and produces bad crashes by overwriting the Mapped ROM, i get a
Red Screen because the ROM now fails it's checksum. You are right, you
CAN only solve this with a power-down, but it is only a temporary fault:
if you disable the board (and Mapped ROM) by holding down <2> on
startup, everything will be fine (no Red Screen - and no 030). If you
were then to re-enable the board by holding down Ctrl-Amiga-Amiga for 10
seconds, the Red Screen would be back! So, don't use badly crashing
software...
This is NOT a hardware problem, although the only way to get out of it
is to power down. There is (probably) nothing wrong with your hardware.
I personally experience these problems only with some badly written
software or betas of MCP ;)
I do recommend the 1230-IV, though.
. It autoconfigures properly, auto RAM-sizing, good memory address
range, etc, fast RAM access! (after all, the memory bus was designed
by Phase V!)
. It can be disabled (great for naff-games, although I'm not the gaming
type).
. It has an MMU, and VMM works beautifully...
. You can use Blizkick or similar on it with MapROM enabled. This will
not only speed up your general operations, but it will allow you to
use ROM extensions like prepareemul (for ShapeShifter), VBRMove (more
speedup!!), etc. BUT, IT EVEN SPEEDS UP MY HARDDISK TO 2.2MB/S!!!
(with FastExec turned on, of course, this is what makes Blizkick such
a beautiful program) (from about 1.6!!!) I'm talking Internal IDE
here, although it is a 2 Gigabyte drive, so it's supposed to be
fast...
. It was already the fastest 030 board, before I mentioned those
improvements ;)
BTW, the AB3dII demo does work. I have used it.
I hope that I have solved ALL of your problems ;)

Some programs has problems if you use magicmenu and crashes if you try to use
menus.

I have also Blizzard 1230-IV, with 16MB RAM. And experienced same thing. It
usually happened when running AmiTCP. The machine froze, or reset by itself,
and had red screen. Had to turn off puter after that, coz reset won't work.
Btw, I am not using maprom, and have set jumper for 60ns memory (since it
is). Btw, this is definitely NOT due to PSU, since I have 200W PSU.
Is this due to some HW error, or is it just some software bug?
Btw, before I buyed blizzard, I had never experienced this thing.
Do other ppl using blizzard experienced this?

I have Blizzard 1230-IV, with 8MB 60ns RAM. and 2 amigas :)
I use powe suply from A500. IT IS NOT POWER SUPLY FAULT BECAUSE I CAN CONNECT
CD-ROM DRIVE ant it didn't affect perfomance of blizzard.
So with my first Amiga:
I've got lots of red screens, locks etc. I discovered that CPU and some custom
chips in A1200 are hot.
I tried to reduce hot from 68030 with fan, used open A1200 etc. nothing help
me. Phaze 5 told me to change SIMM, I do. nothing happened.
When I switched to superhigh res screen (~1200pix) I found some graphic
garbage on screen. I cooled some chips near HD, graphics garbage vanished. But
red screen still was...
When I moved ROM to RAM with blizmagic things become better, but lots of hot
still comming from Amiga's chips (not speaking about CPU)
At last I connected bad printer to my A1200 and fried
8520 :)
I've lost my mouse pointer. Nothing beleaved me. I made special program to
test CIA 8520 and discovered that some counters not working.
I switched to VGA screen modes mouse reapeared. In such stage my A1200 was
working for about 2 weeks. Until my A1200 was gone.. Somebody want to buy it?
So I purchased new A1200... Installed blizzy. It works fine. No crash. Works
fine (tfu..tfu) But after about 2 days of non stop work with Imagine, my HOT
amiga crashed on Monkey Island game (DAMN!) I rebooted. Crash! Oh my God. I
switched A1200 off and after 20s on. Crash! OHHH! I switched it OFF for about
40 minutes. Switch it on. And I can play the game.. Yooff!
If I locate that Blizzy will try to dammage my Amiga I'll send to Phaze5 big
box of ....(internal censor not allowed to type)....
I think, it is some problems with damn commodore and phaze5
designers/manufacturers . Some chips may overheat (not CPU, it is made by
Motorola and I read in data books that: MAX OPERATING TEMPERATURE FOR MC68030
at 50MHz = 70C, STORAGE = 125C YES!)
SO, What to do:
1. look if you Amiga is not hot.
2. Try to swap Amiga and blizzy with your friend. :)
No help? Sorry :)

The problem comes fomo the 60ns dip
it's activates burst mode which crashes many programs
turn off burst mode or turn off 60ns mode
I also have a 123 IV and i tnk if on has te new scsi roms via softscsi
it works morestable wih it's scsi card.
And PLEASE Can someone send me a 3.1 1200 Kickstart image
I boughtthe full 3.1 os kit upgrade but have yet to upgrade the roms of
the 1200 to v 40
I need it so i can finally play chaos engine cd32////
ad other software can work too.
if you don't believe me I ca ginve yu the serial #' and isbn of the box

Hmm... well, here's what I've come to (at least in my case).
I now remembered when first time red screen appeared.. it happened every
time I was using AmiTCP.. But, in earlier time it was all OK. THan I
remembered I added MagicCopper to wbstartup (one from MWB), and after that
this started to happen. Now I removed magiccopper from WbStartup, and
haven't had a crach in some 4-5 days now, and I use 'puter a lot, more than
6 hrs a day.
Oh, also about A500 supply and other stuff you wrote about.
A500 supply is NOT enough for A1200, blizzard, and HD. It MAY work, but it
is NOT reliable!!! Buy PC PSU (200W)!!! I bought one. I would not risk my
'puter to put on A500 PSU. Especially for longer period of time. Your
troubles might also be due to weak PSU. Also, my blizzy also gets pretty hot
after some time, but even after 10 hrs of work, without turning off 'puter,
it's performance doesn't slow down, s it means it is not getting too hot.
(I am thinking of drilling holes in lid where blizzy is, so it has better
cooling, though)

OK. I'll try. But I didn't like the fan in PSU. It is noisy.

Blizzy may become very hot, nothing bad will happen. (I analized databooks
again, and found that 50Mhz 68030 max case temp=80C, 70C for all others)
>it's performance doesn't slow down, s it means it is not getting too hot.
>(I am thinking of drilling holes in lid where blizzy is, so it has better
>cooling, though)
I don't think that the temperature of CPU slows down computer. Maybe, the
temperature of SIMMs.. but I don't think.
Drilling holes near CPU will not help. I experimented with open trapdoor and
glued part of CPU sink from 486 (without fan). The CPU still WAS hot after it.
The worst thing is that Amiga's customs chips are hot. In my bad Amiga, when
chips under HD were hot I've got garbage on the screen.
I am using 2.5 HD and it is quite hot too.
Now I put very small fan from CPU cooler into the gut of A1200. It sucks air
from empty space near HD. The air goes to the hole in shield over the CHIP ram
and goes away near the HD connector. Now the HD and chips near HD are cold.
And ofcourse, the trapdoor is removed. After the long work I can feal the
warm, placing the hand under the table in the place were is CPU :)

in the manner you describe - I got both yellow AND red screens, though I
could always reset from the keyboard. The system certainly was more
unstable than without the card.
Then, all of a sudden, all my problems disappeared for some reason...
As for the inability to reset from keyboard, I think it indicates a
hardware fault, since the keyboard *has* to invoke a reset.
Maybe AmiTCP or some other program inserts its own reset service
routine.
If there was a crash with a program going to the wrong address space,
for example, and miraculously managing to insert a reset service that
does an infinite loop then this might be explained. :)
You should know though, that even in this situation, the Amiga should
finally RESET AFTER 10 SECONDS. Have you waited for this period of
time??

But, I found out what was bugging my Ami!!! 't was magiccopper from SASC
package! Without it, still haven't got any craches :)) (Now for some two
weeks)
So, pp, if u got same crashes, and using magiccopper, remove it!!

I have also had this problem, and I think it is because of the great
amount of heat radiated from the processor. My card had the same problems
so I removed the lid under the computer and voila!, it worked without a
problem. Although later when I tried with a 60ns mem it didin't work! Weird!
The reset problem is probably not the fact that you can't reset but when
you do it the computer crashes again before it even has time to do the reset.
If you check your power led at the same time you press your keys, you'll
probably find them flashing just moments after pressing and the screen will
turn red again.

About RED screen and reset:
When MAPROM switch is enabled ROM is copied to RAM. If you use some Blizmagic
(soft kickstart, fast exec, move VBR...) stuff, Blizzard copy ROM to RAM only
once. So imagine, some very "ugly" program or just "heat bug" managed to
destroy image of you ROM. Your little Amiga calculates check sum of ROM (in
RAM) and you get RED screen. You press reset, mashine initializes again, bad
checksum, red screen and loop forever. If you use only MAPROM without
Blizmagic, after 10 s keyboard reset, original Blizard initialiazation routine
in invoked and new ROM image is transfered to RAM. But if you use some
blizmagic , you can hold reset for any time. Blizard original init code is
disbled. So you must switch of computer for some time.
If you have red screen without maprom:
It is worst situation. Some Amiga internal IC are overloaded. I have two A1200
and one works OK another not. That A1200 who locks with maprom disabled is
a bit defective, I think. I opened it and discovered that: MC68020EC, AA chip
set and BIG chip under hard disk are hot. In good Amiga they are cool.
I used this bad Amiga for 1.5 Years with lots of red screens and Guru until my
amiga was dead. And I don't know how to help. No luck...
Some words about heat:
CPU produces lots of heat. But CPU can work up to 80C and nothing bad happens.
You must protect your RAM SIMMS from heat (especially in they are old and
60ns) The best way is to remove trapdoor. You can use some paper to secure
blizzard from moving.

hmm.. also, it CAN be due to software.
I started getting red screens on my Amiga, when I used MagicCopper with
AmiTCP. Amiga either just rebooted, froze, or started reseting, with red
screen - when I had to switch it off/on, to make it work. After I removed
magiccopper, it works OK ('knock on wood' :))
Btw, I have 60ns 16MB RAM, and maprom is disabled.
