Just press Ctrl-C at DOS prompt! Try Ctrl-Break if it doesn't work.

This doesn't universally work across all OEM versions of DOS, but... The CP/M ritual of using a Control-C to force a re-read of the disk's vitals can be found on some DOS versions. It's not very helpful if you have even a simple disk cache (other than BUFFERS=?? in config.sys) running. The smart way to do it probably involves an ioctl call to the driver. -- Bob Bob Izenberg cs.utexas.edu!dogface!bei [ ] "So young, so bad... So what!" 512 346 7019 Wendy O. Williams
