I recently installed 32 Bit 14.04 on my old XP computer. It seems to have installed without issues, however all of the RAM is not being recognized. In the system info it says 2.4 GiB, I believe I have 1024 MB installed.
This is what I can tell you about my computer. P4 2.6 GHz Graphics 8656 x86/mmx/SSE2
