Same solution, move IDE1 slave to IDE2 master.
Check dmesg.boot file for boot messages about hard drives and their speeds.
ATA66 should be your fastest drive and the one that you want FreeBSD on, and
it should be the master on IDE1.

Thanks for the reply.
Yes, i do have two hard drives in my server. I am not sure about their
speeds. Could you please give me the solution if the problem is from having
two hard drives.

These means that you have a mismatch between the devices and the
ribbon connecting them to your motherboard. Most common cause is a
UDMA66 hard drive plugged into the master connector on the ribbon
and a UDMA33 CDROM. The messages is telling you the IDE hard drive
controller is defaulting the ribbon read/write speed to the slower
speed of the CDROM.
Now this is not harmful to your hardware, but does deny your server
the ability to utilize the full speed potential of your hard drive.
This is easily fixed by moving the CDROM drive from the slave
connector on the primary IDE controller to the master commenter on
the secondary IDE controller on your motherboard.
This also can occur if you have two hard drives on the primary IDE
controller of different speeds.

This morning I have seen the following log message on my FreeBSD 4.7
ad2: READ command timeout tag=0 serv=0 - resetting
ata1: resetting devices .. ad2: DMA limited to UDMA33, non-ATA66
cable or device
I would really appreciate if someone could tell me the cause for
this message and is there something to worry about the server?.
Thanks in advance.
