[Coco] So does your coco3 do 256 color mode ? Mine does...

[Bill Pierce]

Luis,
Why not do it in the "startup" file?
You will no have no display during the boot, but the startup is run before the os9 prompt is reached, so you will get a display then. Be aware that the OS9 font/pointer/pattern files have a "load" header. I'm not sure of the format, but I know it's documented somewhere.
I'm not sure how much functionality exists in intit, others can answer that better. It seems to me that what you're trying to do, should be done in the driver init as you suggested. It should be doable.

But I will have to make a L1 driver and I need to send 2K of patterns
to the VDP prior the booting.

In the init of the covdg.io for example is the files system already up
and can I open and load  a file inside the os9 file system ?
