I needed RLL support, so I changed the number of sectors for one entry from 17 to 26. I changed the next entry from 17 to 8. Note that this also means you only have to modify/burn one chip. Completely changing an entry (numbers of head, cyls, etc) doesn't work. Please let me know if you find the location (or a byte pattern) of the checksum code. -- Jon Zeeff Branch Technology, uunet!umix!b-tech!zeeff zeeff%b-tech.uucp@umix.cc.umich.edu
