That means your controller or drive is out to lunch. Timeouts are only supposed to happen if there's no medium in the drive. (This is due to one of the most botched parts of the PeeCee ``architecture'', some genius of an engineer at IBM dropped the READY signal from the floppy bus, and wired the READY pin of the FDC to +5 V. So the controller now thinks the drive were always ready, and your only chance to notice that it's actually not is timing out an attempted command.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
