How to create and set up a hard disk image for the Geneve driver (MESS)

Special thanks goes to mizapf for helping me to understand the procedure.
Vielen Dank, Michael!

You need:
chdman
editor_assembler.rpk (cartridge)
setup.dsk (Myarc Disk Manager 5 V1.50)

1.) Create a hard disk image
chdman createhd --output blank20mb.chd --chs 615,4,32 -ss 256

2.) Format the hard disk
We'll use the Myarc Disk Manager (setup.dsk) which runs on the ti99_4ae driver.

Start the MESS/ti99_4ae driver with the mounted devices
Command line:
mess ti99_4ae -keymap -keymap_file keymaps/km_de_LINUX.map -peb:slot8 hfdc -hard1 blank20mb.chd -flop1 setup.dsk -cart editor_assembler.rpk

Enter Editor/Assembler, menu option 5 (RUN PROGRAM FILE), enter DSK1.MDM5

Press (E)xit, the time should be correct
Press (U)tility
Press (F)ormat
Press (H)ard, enter number 1

Wait a second while the hard disk is probed.
Provide a volume name, like HARDDISK (max 10 chars).

Geometry: (recall what you used in chdman)
32 sectors
4 heads
615 cylinders
Reserved: 2048, keep that
Write precomp: 464, keep that
Reduced write curr: 464, keep that
Retry: 8, keep that
Interlace: 3, keep that
Step: 1, keep that
Enter the "operational code": FORMAT

Wait until all cylinders are formatted (615)
There should be no error, anything else is a bug to be reported.

Leave MDM5: (E)xit, (Q)uit, (Y)es

Exit the TI-99/4A emulation.



3.) Start the MESS/geneve driver with the mounted devices
Command line:
mess geneve -keymap -keymap_file keymaps/km_de_LINUX.map -peb:slot8 hfdc -flop1 setup.dsk -hard1 blank20mb.chd

The Geneve should boot (takes about 20 seconds).

A blue welcome screen appears with a message. Follow the instructions.

Restart the Geneve when done. You can now unmount the floppy disk image.
