Jenze LOADLIN vyzaduje DOS,  Muzu mit bootovaci ZIPku s DOSem ale ta zas
nema partitiony, behem nekolika okamziku se do toho tak zamotam ze to uz
bude lepsi skocit z okna.

no vrazil jsem tisky primo na konec geo_query_dev() a vyslo mi toto:

aj aj aj, to to boli, v teto chvili se obvykle s prihloplym vyrazem v tvari
ptam "a co to je ten DOS, da se to jist?"

mam vsude jen linux na nekolika desitkach stroju.

Navic, pokud se dobre pamatuji bych toho asi moc nezjistil.  ZIPka "dynamicky"
meni behem bootu sama sebe.  T.j. v jednom okamziku je to FLOPPY
a v nasledujicim HD.  Tusim ze dokonce kvuli tomu modifikuje (mechanika) data
ctena z diskety.
