Longshot but figured I'd ask has anyone ever seen a FCode dropin Example for Openboot or Openbios? If you every come across such a thing I'd love to see it.
I'm talk pure Fcode that you could enter into the NVRAMRC and then call at boot.

Added just for my own notes...


On Ultra 5/10 these dropins exist

The "class010100" is the generic IDE driver. This is the one I really really want to see or figure out how to tweak.

I can make a class018000 via the nvramrc

2: : class018000
3: " class010100" do-fcode
4: ;

This creates an IDE device for my card fine and the child devices are found (disk and cdrom) BUT the children can't seem to do DMA2+

the Disk has output from the block-size and max-transfer equal to the internal IDE bus.

ok see block-size
: block-size
(f00875d8)
;
: max-transfer
(f00875d8) 40 *
;


But that might be red-herring... If I could just see the fcode source on class010100 I'm sure I got fumble through a fix.

If you know the start address and length of the snippet isn't it possible to dump the binary part into some file and use the detokenize tool to get the FCODE source?
