I have a hazy memory of Corel's distribution coming as a free CD-ROM in a PCI network adapter I bought from CompUSA. Installed it, used it for two weeks, went back to... I think it was Mandrake I was using at the time. Am I going senile?
No, I'm pretty sure I got a copy from a flatmate who bought a USB ethernet adapter and it came with Corel Linux on a CD. This would have been about 2001. Don't think I ever installed it though.
