CD-R HP 4021 (pokrok)

[Snek]

Vzhledme k nepeknemu obvineni ze lzu a moji touze vypalit CD pod Linuxem
jsem si vcera opet pohraval s vypalovackou HP.

Jedina lez byla ze neni treba u moji vypalovacky upgradowat frimware,
jelikoz mam posledni verzi 1.25. Timto se vam omlouvam a doufam ze se
zamysli nad sebou i dotycny pan programator.

Jinak k veci.

Zjistil jsem ze pokud prelozite podporu pro SCSI jako moduly a zavedete jej
pomoci INSMOD tak se vypalovacka zacne chovat uplne jinak! Lze ji pouzivat
jako normalni CD-ROM. (pokud je SCSI v jadre primo tak ani necte CD-ROMy)

Pri pokusu o vypaleni nebo cteni vice jak 20MB zacne opet vypisovat chybove
hlasky.

Dival jsem se take do zdrojaku radice AdvanSys (mam ABP5140) a je tam zminka
nejakych zmen k HP 4020, bohuzel jsem nepochopil co stim.

S pozdravem Snek ;-)
