I tried to access an UHID device using FreeBSD (4.10) and I'm a bit
confused. I did the same thing before with NetBSD and expected the
device to behave the same under FreeBSD, because the man pages are
pretty much the same. Two things I've noticed:
- There is an man page for uhidev(4). uhidev
Hi,
I'm having problems with getaddrinfo call.
When resolving multiple IPv6 addresses that are specified in /etc/hosts, the
response from getaddrinfo call contains only the first address not the whole

I have a DVD drive which is recognised by FreeBSD:
acd0: DVD-R DVD-RW IDE1004 at ata1-slave PIO4
The drive supports DMA, and Windows sets it to use UDMA mode 5 (I
think), but BSD does not.
I am assume because the device is not listed as supported correct
driver?
I had a look in ata-dma.c but

Can anyone point me in the right direction for this?
have you tried man ata ?
The following tunables are settable from the loader:
hw.ata.atapi_dma
set to 1 for DMA access, 0 for PIO

This may go without saying, but have you read Chapter 22 of the FreeBSD
