okay now I know that NT,2k and XP don't support arcimg but I've been trying to get it to work. Now i've tried a windows 98 boot disk (as suggested on these forums) and a windows XP boot disk and i managed to get arcdisc to load, detect the 800k acorn disks I tried, but just as it gets on to the reading to adf image stage it crashes with the error:

runtime error 005 at 0000:0E74

I just wondered if anyone knew what this meant:)
Thanks.

(im not too bothered as there's a win98 here I can use but if we can get past this runtime error I really do think we will have an XP arcimg).
