Duncan, or anyone else with experience in this, I've installed Scientific Linux 3 (which is a rebadged RHEL3) on my new laptop (IBM ThinkPad), but it doesn't recognise the wireless network card, an Intel Pro 2200BG. Looks like Intel's driver requires kernel versions >=2.6.8. SL3 has 2.4 kernels. Scientific Linux 4 apparently has a 2.6.9 kernel. Questions: 1. does anyone have useful experience with getting IP2200BG working under linux? 2. does anyone have experience with Scientific Linux 4 and/or RHEL4 (which it's a copy of)? It claims to come with backward compatibility libraries so I guess things that work on RHEL3 (like building/running the USSC) ought to work, but you never know... I'm not deeply committed to Scientific Linux, but Rhys suggested it was a good choice. cheers Mark -- Mark Taylor Starlink Programmer Physics, Bristol University, UK [log in to unmask] +44-117-928-8776 http://www.star.bris.ac.uk/~mbt/
