Dear all,

although I posted a previous email to the list about this issue some
months ago, I thought I would check again to see whether anything has
changed with the 7.1 release.

I have an LG cd/dvd combo (model GH22LP20) that attaches to the
PATA(/IDE) connector of an Asus P5Q Pro motherboard.  The specs for
the motherboard are the following:

N=B0 sockets (max memory): 4xDDR2 (max 8GB)
Chipset: Intel P45 (LGA775 platform)+ ICH10R
Sound Card: Realtek ALC1200 7.1 Channel High Definition Audio
SATA support, N=B0 connectors: 8x SATA2, 1x PATA
LAN: Atheros AR8121 10/100/1000 Mb/s
RAID: 0,1,0+1,5
Connectors:
   * 2 slots for PCI Express 16x 2.0
   * 3 slots PCI Express x1
   * 2 slots PCI 2.2
   * 12 x USB
   * 2 x Firewire


The PATA-133/IDE interface is implemented via an additional Marvell
88SE6111 controller (SATA is driven via ICH10R).

My problem is that the DVD drive is not seen by FreeBSD, although it
is seen by the BIOS in the boot up phase.  In the previous post Jeremy
Chadwick kindly pointed out that the Marvell 88SE6111controller may
not be supported by FreeBSD.  I was wondering if this is still the
case with the 7.1 Release and whether somebody could suggest a
workaround that does not involve replacing the drive (e.g., is it
possible to use some sort of converter cable from SATA to PATA?  I
apologize if this is complete nonsense, but I know virtually nothing
about buses and connector types).

By the way, if this may be of interest to other users, the Atheros
onboard NIC appears to work fine with the driver "ale" (disabled by
default in the GENERIC kernel), and sound works too with the kernel
module snd_hda.

thanks in advance for any suggestion

very best

  giuseppe
