Gigabit Ethernet at last

Ever since I got hold of my Ultra 60 workstation I have been trying to get a Gigabit Ethernet PCI card working in it under NetBSD. But neither a 3Com 3C996B-T nor an Intel PRO/1000 MT card worked in that machine because of problems with PCI interrupts.

But thanks to Julian Coleman and Rafal Boni the problem got fixed finally. The Intel card is now working fine under NetBSD 4.99.52:

wm0 at pci1 dev 1 function 0: Intel i82540EM 1000BASE-T Ethernet, rev. 2
wm0: interrupting at ivec 0
wm0: 32-bit 66MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:07:e9:XX:XX:XX
makphy0 at wm0 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto

The network performance is not great yet but it is a step in the right direction. Now I wait impatiently until Martin Husemann finishes the work on SMP for NetBSD/sparc64.

An unintended Lecture

Never volunteer on a mailing list to give somebody a quick introduction into OpenLDAP! You could end up with twenty people listening to a presentation about LDAP in general which you have to come up with off the top of your head.

It happened to me yesterday and fortunately went quite well. I had a bit help from the audience and a lot of people realized soon that they already encountered LDAP as Active Directory.

Despite being somewhat unprepared I enjoyed giving that lecture. And I’m foolish enough to believe that the audience enjoyed it as well. 🙂

Long live the Printer!

A few weeks ago I bought some spare parts for my old HP Laserjet 4 because it couldn’t print a single page without a paper jam anymore. But neither my fabulous hardware department nor I had the heart to attempt a repair so far because we didn’t have instructions how to install the spare parts.

Luckily for us our good friend Achim is currently visiting us with his family. And because Achim isn’t afraid of anything and has healing hands when it comes to repairing computer hardware he retransformed our paper shredder into a printer today.

The only drawback is that I no longer have an excuse to buy a new colour laser printer. 🙂
