I have an Epox 8RDA+ motherboard, MSI TI4200 video, 1Gb RAM, AMD XP2500+, dual-boot (Linux Mandrake 9.1/W2k), DVD-ROM, Yamaha CD-RW and 6-way flash card reader. I ended up installing Mandrake 9.1 with only 512M RAM initially. After I had done all the updates, I installed the second 512M stick and everything seems to work smoothly. I had a hell of a time doing the install with the 1G installed.
I had tried all the other install messages, but none work for me.
Hope this helps.
