Need to try and keep kernel under 48K or so to make it easier to handle the
screen memory, fonts etc. We need to put the screen (720x256 pixels + roller
ram table of 512 bytes or so = ~ 24K) in the low 128K

+Building A Boot Image
+---------------------
+
+edit Makefile and set it to z80, platform pcw8256
+make clean; make
+cd platform-pcw8256/BOOTBLOCK
+zmac 765.s
+
+
+# Make a blank disc
+dd if=/dev/zero of=bootdisk.raw bs=512 count=360
+# Add the boot block in sector 0
+dd if=platform-pcw8256/BOOBLOCK/765.cim of=bootdisk.raw conv=notrunc
+# Add the kernel
+dd if=fuzix.bin of=bootdisk.raw bs=512 seek=1 conv=notrunc
+
+# Start the emulator
+xjoyce
+
+Hit F3 (Boot from alternative disc)
+Boot From
+ =>Other
+Enter filename for disc image
+ Disc file...
+ select bootdisk.raw
+ Advanced
+ Raw disc image file
+ OK
+ OK
+
+Should boot and detect the drives then prompt bootdev:
+
+At that point the keyboard should work.
+
+The floppy driver is incomplete but given a rootfs image on /dev/fd1 you
+should be able to at least get it to mount
+
+device 0 = fd0 1 = fd1
+
+
+Mixed boot/root images are not currently supported (this just needs a modified
+boot block that starts at a different offset)
