Hi Hugo, In some circumstances (can't remember what they are at the moment although I can refresh my memory from the code if necessary) RPCEmu skips the first 512 bytes of a hard disc image (see "ide.ski512" in ide.c). I have a feeling I couldn't get one of my hard drive images recognised until I prepended 512 bytes of zeros to the beginning of it, so you could try doing that. To clarify what I mean, here's one way of doing it in Unix: # create new.img as a copy of old.img but with 512 bytes of zeros prepended dd if=/dev/zero of=new.img bs=512 count=1 cat old.img >> new.img Francis _______________________________________________ Rpcemu mailing list [email protected] http://www.riscos.info/cgi-bin/mailman/listinfo/rpcemu
