I have used (and continue to use) Vector Linux 5.8 Std. on a Compaq Armada 1700 laptop. I tried an install of VL 5.9 on the Armada but ran into problems because the latest release will not run the cooling fan and the laptop overheated during installation. Back to 5.8 there.
However, I have successfully installed VL 5.9 on a 1999 era Compaq Presario 5360 desktop system. This old desktop has a K6-2 450, 100 MHz bus and I've upgraded it to 320 MB RAM.
When I tried VL 5.8 a few months ago, I got a very bad display thanks to the Compaq's very Linux unfriendly SiS 630 onboard graphics. I replaced the onboard card with an ancient ATI Xpert98 video adapter and used the ati open source driver.
With this combination I have now got a beautiful user friendly operating system that works pretty fast compared to Gnome or KDE based distros.
I had to add acpi=force and pci=noacpi to the boot options in order to to get the Presario to power off - while at the same time avoiding some misunderstandings between X and ACPI that were resulting in rrreeeppppeeeeaaatttiiiinnngggg letters when typing in graphical mode.
I'm hoping to give this refurbished system away to someone in my town who doesn't have a computer.
