18 yeah, I got that, I was just picking on your use of ketchup & baseball.
19 Over here it's tomatoe sauce (dead horse) and cricket (baggy greens) :)

25 Perhaps something to do with the superblock or "last mount time" or
26 something? I don't know! I know that mounting a drive while a system
27 is hibernated, even ro, will kill kittens.

38 well there appears to be no RAID controller, unless it's onboard, but as
39 I mentioned to Francessco the BIOS can see all drives, so can gentoo
40 minimal...

42 I've since found that the OS is in flash RAM, and only the help files
43 are on disk, so maybe I have bigger problems if I can't boot :( I hope
44 to get a copy of Guardian OS somehow...
