Description of reset 'sequence'

[Chain]

Hi A11,
where i can get deep description - something like "How things inside amiga works after keystroke Ctrl-A-A"?
I still have problems with one of my A1200. Some signals are sended after reset, but miggy cant boot, no floppy seeking, only black screen.
There must be big difference between 'cold' start and restart.
Any ideas? Help of any kind desparately wanted. :-(

Absolutely NO PATCHES, only bootscreen or early-startup menu.
I want to know something like this example:

0. start, power up
1. paula send xxx into xxx, this make  xxx
2. all registers set to 00000 blah blah
....
blah
....

15. Insert floppy screen appears.

WOW, thanks!
So think i have some problem with CIA:
BLACK CIA (U7/U300) problem If not booting

Where i can get those ROM kernels descriptions for A1200?
Im making some little repairments too, those damn colors arent in A1200 service manuals!

Just another little thing:
When reset fails, Alice and CPU is very hot after few seconds.
I think there must be some very intensive cycling operation, damn

A1200 tower reset from TP2 pins does not work too, guys
