Re: Bootstrap and boot blocks
My CFX-II fails with InnoDisk iCF-2000 I've had fun with this card with my own boot ROMs and it seems to take longer than many to initialize and respond post reset. For the CFX-I I will add theoretical support and loader as I go but it'll need someone else to test everything but the video fallbacks....

Re: Bootstrap and boot blocks
So I've done a bit more work on it to add SD card (not tested but should?? be trivial), 80 column card probing and surviving on 40 columns only. I've added the basic bits for CF1 (not tested). Right now CF1 needs a different kernel build. I'd expect it to work as it's all library code that's the sam...

Re: Bootstrap and boot blocks
@Dave It implements a fairly full classic Unix compatible kernel and file system - the command line shell is the real bourne shell, most of the general utilities are there, I has assemblers and linkers but the C compiler and a native basic are ongoing projects. It can also run CP/M apps although rig...

Re: Bootstrap and boot blocks
One via the VDP, one via the 80 column card with shift-F1 shift-F2 on the keyboard switching where the input goes. If you have a comms card you add more users on the serial ports, although I suspect four users doing much more than editing documents would be fairly sucky on a 4MHz CPU

Re: Bootstrap and boot blocks
Ok that makes sense..once I knew it only gave me 128 bytes. Is the stuff that CP/M does calling via 0xFFF9 documented somewhere. I can see the call ends up loading 0x34 sectors to CE80 but not how you set which sector to start or what happens if you call it multiple times. For now I've just squashed...

Re: Bootstrap and boot blocks
Been there, done that, already runs across a range of Z80, 6809 and 68000 platforms :D https://github.com/EtchedPixels/FUZIX All I need right now is the information on the boot behaviour. The rest works - at least on MEMU. As ever that doesn't always mean it runs on the hardware because emulators ar...

Re: Bootstrap and boot blocks
The CF card with it works fine for CP/M. However I am not trying to run CP/M but load and run my own OS on the machine.

Bootstrap and boot blocks
Can someone point me at useful documentation for how the boot environment works. I've got my OS loading (from CP/M) on the CF-II and getting to the point it wants a file system. Whilst there is still all sorts of other stuff to fix I'd really prefer to be able to boot it directly so I can put things...
