How to use PC3000 ISA (Summary)

Use "safe mode" jumper setting only when the drive "hangs during start" or does not start without the safe mode jumper.
Why? Because "safe mode" has drawback:
We won't be able to load defects table from the firmware zone.
(Manual book section 7.1)

Find a working LDR file (and its associated .RAM file?) from Internet and put it on the root folder of PC3000
(We can also use "Create an LDR file" if we have a functional drive)

Load an LDR file

Modules loader

Standard mode [?]

Work with firmware zone

Read modules

Read groups of modules

Test firmware zone recording
(Manual book section 7.1)

Check firmware structure
Make note if any of these modules is damaged:
DMCS, U_LIST, AT_POL (G-List), AT_PDL (P-List)
Damaged/corrupted modules can be identified by their strings displayed with:
NO_PLIST, NO_GLIST, NO_DMCS

Exit program

Examine created folder for bad modules (has extension of .bad)

Copy files of good modules to the same folder (?)

Start program

Perform "Write modules" (?)

Repair header modules:
Firmware data > Work with firmware zone > Restore modules
(Manual book section 7.2)
