This will happen sometimes if the cable is reversed. There is one = connector that should be labeled specifically for the motherboard (or is sometimes = a different color). If a standard 3 connector cable, its the one by = itself, vs the 2 that are spaced a few inches apart. Maybe people reverse the cable because of length problems (speaking from experience...). > -----Original Message----- > From: owner-freebsd-questions@freebsd.org=20 > [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Ugo=20 > Bellavance > Sent: Thursday, July 24, 2003 7:58 PM > To: freebsd-questions@freebsd.org > Subject: DMA limited to UDMA33, non-ATA66 cable or device >=20 >=20 > Hi, >=20 > --System > FreeBSD 4.8 release > It is a kernel that I recompiled only to enable SMP.=20 > The same error comes with the generic stock generic > Kernel. > It is a dual Athlon MP 1800+ on a tyan MB.
