- Gayle style IDE is very simple, i've been looking into it. though bluea would probably be the best person to ask about it, he has it working on natami i believe. Most of the signals come straight from the CPU, which means very few FPGA pins will be needed.
- from what i can see, the only lines that dont come straight from the CPU are.
- IDE_CS1
- IDE_CS2 (usually only used by IDE doublers, can probably be left out)
- IDE_IRQ (not needed when interfacing drives to MCU's, not sure whether scsi.device needs it)
- IOWR
- IORD
- WAIT
- what do you know... exactly 6 extra lines
- The data lines are byte swapped
- And IDE_A0 - IDE_A2 are mapped to A2 - A4
- finally, IDE_LED, optionally goes to an LED.
- an IDE only mode compact flash port, could easily be added to the bottom side of the board. :Giving us access to 1.8" hard drives.
