Hi Max,
No problem, your English is fine.
I'm from the Netherlands and have the same problems sometimes
The easiest way is the MyIDE+flash cartridge.
That works nicely with a female-ide-to-cf adapter
(search on -international- ebay on these words. You find them for less then 2 euro)
and CF-cards.
The internal MyIDE+flashBIOS needs you to desolder the OS-rom, solder in a socket and place the interface.
Not recommended for unexperienced users.......
Works also great with a CF-setup.
Later,
Sijmen.
