Could someone tell me how to specify the word on which to sync an MFM read using the TD_RAWREAD command? I know you have to set the indexsync bit in the flags offset, but I cant figure out where to put the sync word. Ive tried putting it directly into the $dff07e register, but that doesnt work. I know my code works because I can switch the command to TD_READ and it works fine, but its in DOS format. I need raw MFM.. I know its not syncing correctly because I get completely different data each time I try the MFM read.. Into what structure or what location should I put my sync word? Thanks tremendously, Jim
