HP Omnibook 2000CS (danu)

The video chipset, the Chips and Technology CT65554, is supported with acceleration by the generic SVGA server included with XFree86 3.3.6. Performance on a dual-scan LCD is not fantastic, but I get 16-bit color with an 800x600 panel. I have successfully used this LCD and an external display simultaneously under X Windows. The relevant parts of my XF86Config file are available here. Use it at your own risk!

I'm running GNOME 1.0, but since the backlight died and I mainly use this as a printer/file server, I usually just ssh into the machine over my home network.

With Red Hat Linux 7.1 sound is supported by the cs4232.o, uart401.o, and ad1848.o loadable kernel modules. Here is my /etc/modules.conf file.

With this and newer kernels, APM (Advanced Power Management) support is provided by default. I used to run Red Hat 6.0. For this version, to get APM support I needed to recompile the kernel. This is not hard, but to do it with some confidence you need to read the appropriate Linux HOWTOs first (particularly the Linux Kernel HOWTO). With APM enabled I used to get about 2.5 hours of life from the machine's lithium-ion battery. It's plugged in all the time now, and the battery probably has less life in it now.

One small glitch: the lack of L2 cache hurts floating-point performance on some problems. I get about 8.5 Mflops on the Linpack benchmark (the CPU is a Pentium 133); on my old P133 desktop machine, which had 512K of L2 cache and an Intel HX-based motherboard, I got about 11 Mflops. I'm curious as to whether I can add L2 cache, since the BIOS appears to know it's not installed, but so far I haven't found a definite answer to the question.
