Re: 9/1 snapshot on Dell Precision 380 w/Intel dual-port GigE card

Just replying to my own mail to get my findings into the misc@
archives. Perhaps it'll save someone else some time since I've
found partial solutions to my problems.

Thanks to Jonathan Gray for his help and pointers -- I wouldn't
be able to figure all this out otherwise.

First of all, the Dell Precision 380 workstation will NOT work
with OpenBSD 3.7 even with the following workarounds.

I have not tested OpenBSD 3.8 yet, but have verified that
-current works reasonably well with the following workarounds

I had difficulties installing OpenBSD-current (the 9/1 snapshot) on
a Dell Precision 380 (manufacturing date: 07/23/05) with an Intel
dual-port gigabit Ethernet card (em(4)). The installation was done
using a home-brewed bootable CD.

I encountered the following three problems and I hope someone can
help or point me in the right direction.

Problem 1 ========= The CD booted fine, but the keyboard hanged at the "(I)nstall, (U)pgrade or (S)hell?" prompt. I noticed in the dmesg (below) that several devices were not recognized, so that's probably the problem. Could SATA be part of the problem too?

The PS/2 keyboard hung because of bugs in the Dell Precision BIOS (version A02 at the time of writing). As a workaround, disable USB support in the BIOS with the following steps:

On boot, enter BIOS setup and change the following:

Onboard Devices -> USB Controller -> Change "On" to "Off"

Relevant info:


The next version of the BIOS is supposed to fix this problem, but
Dell has not released it:


As an aside, all devices are recognized now. Thanks to Jonathan
for committing the relevant diff to pcidevs.

Problem 2
Since the keyboard hung, I tried installing using the serial
console. This time the OpenBSD installation program said that
no disks were found (see serial console output below).

You have to disable AHCI for the disk to be detected.

Enter BIOS setup and change the following:

Drives -> SATA Operation ->
Change "RAID Autodetect / AHCI" to "RAID Autodetect / ATA".

Problem 3
The dual-port Intel card was not recognized, where the dmesg
said "The EEPROM Checksum Is Not Valid". I found similar
reports in the misc@ archive, but there were no solutions.


The Intel card is an Intel PRO/1000 MT Dual Port Server Adapter
(product #PWLA8492MT). The packaging has the following details,
if it's relevant.

Date: 10/18/2004
Version: A85400-006

I suspect it's a new Intel card that has been marketed with the
product number of older Intel cards, and that's probably why
the em(4) driver did not like it.

Still no solutions with the Intel dual-port gigE card. Anyway if you're reading this because you're having problems with the Dell Precision 380 only, this will not affect you.

See this thread for recent updates:


I'm pretty stuck right now, so I'll really appreciate any help
on how to troubleshoot the above problems. I have tried to
provide as much details as possible, but if you need further
information, please let me know.

dmesg and serial console output are appended below.

The original dmesg and serial console output with the September 1 snapshot are at:


The new dmesg for the Dell Precision 380 with the October 27
snapshot is appended below.
