Right, but in some cases they are shared or at least irq15 is on some older systems, typically with at network card or SCSI controller. However this didn't work before either as the previos ATA code didn't check DMA status this early (which failed in other interesting ways, catch22 as usual)... -Søren _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
