I am working on porting the minimig to the Cyclone III FPGA.
So far, everything looks good. The only issue is the floppy drive emulation
I cannot get the "hand" screen under KS 1.3 or the disk animation under KS 2.0.
With KS 2.0, DF0 is recognized in the boot menu.
Any ideas ?
BTW, I improve sligntly the kickstart loading speed by using double buffering in the bootloader : I DMA 16KB of data in buffer #1 while copying 16KB of data from buffer #2 into KS area and vice-versa. DMA is constantly on (213KB/s with DMA floppy acceleration).
