It has just two USB ports, one VGA, one Ethernet RJ-45 and one Compact Flash adapter to IDE in the motherboard. However, since kernel 2.6.24.7 that i am not able to boot the kernel anymore. It stops right after being copied to RAM. I would say that the kernel don't even start, because the message "Software is Loading..." just stays on-screen. I have tried 2.6.25, 2.6.25.2, 2.6.26.3 and 2.6.27-rc7 with no success on any of them. I would say something has changed in the ELF format since 2.6.25. Could anyone give me some hints on this? There is a small but strong community holding on to this Penguin.
