Postup zprovoznění pod Linuxem

Treba v jadre:
- povolit emulaciu SCSI pre IDE
- zakazat podporu IDE/ATAPI CDROM
- Povolit podporu pre SCSI disk a SCSI CDROM
- Povolit multiply LUNs
Popis nastavenia parametrov a prekladu jadra v /usr/src/linux/README


Parametre v /usr/src/linux/.config dolezite pre konfiguraciu PD-CDROM
Vyskusane pre jadro 2.0.36 z distribucie RedHat 5.2 a Mandrake 5.3

Poznámka

PD/CDROM pracuje podla typu vlozeneho media bud ako CDROM alebo ako opticky disk. CDROM pracuje ako zariadenie /dev/scd0, nie /dev/sr0 ako sa vypisuje po starte. PD cartridge pracuje pod /dev/sda. Pracuje s ext2 aj vfat. Je dobre pokial sa nezapisuje na PD cartridge montovat ho s parametrom read only. Medium ma zivotnost 500 000 zapisov a UNIX-y pomerne casto zapisuju udaje do super bloku namontovanych zariadeni. Zbytocne by sa znizila zivotnost media. Viac v Optical-Disk-HOWTO.
