I probably should have written - it seems to be a problem with ahc. In general SCSI seems to work, as Scott has recently documented.

I can say that at least with my Gigabyte GA-M61P-S3 I observed data corruption with 4GB of memory installed and with the BIOS mapping a part of memory above 4GB. Forcing the kernel to use only 3.5GB solved the problem. --- Gary Jennejohn _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
