bootovani z CF karty

[gatilo]

A zkusil jste nejakej novejsi program pro praci s FLASH kartama.
DOSovskej fdisk preci jen byl psan pro trochu jinej ucel.
Kdyz chci, aby mi fotak "bootoval" s SD karty, musim ji pomoci jakesi
utilitky nastavit jako bootovaci. Vim, ze vas pripad je jiny, ale kdyz
zatim nikdo neprisel s nicim lepsim, tak snad alespon tento tip.

S pozdravem Pavel
