As I comphrend the problem as dedcribed to me, the fear is that some use the same I/O bits generically to control things such as FLASH memory, while others use the same bit to flash (ugh!, an awful pun I didn't notice at first) the LED. So FreeBSD takes the only available common ground and does nothing. You could add this line to your kernel config and probably get your flashing LED back. Works for the Asus SC875. Have heard it makes a mess of the FLASH or EEPROM on a Tekram. options SCSI_NCR_SYMBIOS_COMPAT Having tried this on my machine, the LED flashed so fast and was on so little that it wasn't any fun to watch. So I took the it out the next time I built a kernel. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
