I think it's very valuable boot device for sparc64 and really like to add fdc(4) for sparc64. The fdc(4) patch I wrote basically worked but dd(1) performance on Ebus based ultrasparcs was poor when a single block(512bytes) is used. The same issue was observed on some old i386 machine too but the root cause is not yet known. -- Regards, Pyun YongHyeon _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
