I've got a 512 MB DOM in RaQ4. Can't see a reason why a 1-2 GB (or larger) will not work

40 pin (with 4 pin standard power connector), first fitted on IDE2 so I could flash it (as /dev/hdc) than swapped to IDE1 to use it

I still prefer to use Dave's flash optimized images for it, very easy to install and with write reduction inplace, the DOM will probably easily out-live the RaQ unit.
