If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or any other SCSI device under Linux, say Y and make sure that you know the name of your SCSI host adapter (the card inside your computer that "speaks" the SCSI protocol, also called SCSI controller), because you will be asked for it.
You also need to say Y here if you want support for the parallel port version of the 100 MB IOMEGA ZIP drive.
This driver is also available as a module ( = code which can be inserted in and removed from the running kernel whenever you want). The module will be called scsi_mod.o. If you want to compile it as a module, say M here and read Documentation/modules.txt and Documentation/scsi.txt. However, do not compile this as a module if your root file system (the one containing the directory /) is located on a SCSI device.
If you want to use a SCSI hard disk or the SCSI or parallel port version of the IOMEGA ZIP drive under Linux, say Y and read the SCSI-HOWTO, the Disk-HOWTO and the Multi-Disk-HOWTO, available from < http://www.tldp.org/docs.html#howto>. This is NOT for SCSI CD-ROMs.
This driver is also available as a module ( = code which can be inserted in and removed from the running kernel whenever you want). The module will be called sd_mod.o. If you want to compile it as a module, say M here and read Documentation/modules.txt and Documentation/scsi.txt. Do not compile this driver as a module if your root file system (the one containing the directory /) is located on a SCSI disk. In this case, do not compile the driver for your SCSI host adapter (below) as a module either.
This driver is also available as a module ( = code which can be inserted in and removed from the running kernel whenever you want). The module will be called sr_mod.o. If you want to compile it as a module, say M here and read Documentation/modules.txt and Documentation/scsi.txt.
If you want to use SCSI scanners, synthesizers or CD-writers or just about anything having "SCSI" in its name other than hard disks, CD-ROMs or tapes, say Y here. These won't be supported by the kernel directly, so you need some additional software which knows how to talk to these devices using the SCSI protocol:
For scanners, look at SANE (<http://www.sane-project.org/>). For CD writer software look at Cdrtools (<http://cdrecord.berlios.de/old/private/cdrecord.html>) and for burning a "disk at once": CDRDAO (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>). For other devices, it's possible that you'll have to write the driver software yourself. Please read the file Documentation/scsi-generic.txt for more information.
If you want to compile this as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read Documentation/modules.txt and Documentation/scsi.txt. The module will be called sg.o. If unsure, say N.
This driver supports all of Adaptec's Fast through Ultra 160 PCI based SCSI controllers as well as the aic7770 based EISA and VLB SCSI controllers (the 274x and 284x series). For AAA and ARO based configurations, only SCSI functionality is provided.
If you want to compile the driver as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read Documentation/modules.txt. The module will be called aic7xxx.o.
This driver supports all the features of recent 53C8XX chips (used in PCI SCSI controllers), notably the hardware phase mismatch feature of the SYM53C896.
Older versions of the 53C8XX chips are not supported by this driver. If your system uses either a 810 rev. < 16, a 815, or a 825 rev. < 16 PCI SCSI processor, you must use the generic NCR53C8XX driver ("NCR53C8XX SCSI support" above) or configure both the NCR53C8XX and this SYM53C8XX drivers either as module or linked to the kernel image.
When both drivers are linked into the kernel, the SYM53C8XX driver is called first at initialization and you can use the 'excl=ioaddr' driver boot option to exclude attachment of adapters by the SYM53C8XX driver. For example, entering 'sym53c8xx=excl:0xb400,excl=0xc000' at the lilo prompt prevents adapters at io address 0xb400 and 0xc000 from being attached by the SYM53C8XX driver, thus allowing the NCR53C8XX driver to attach them. The 'excl' option is also supported by the NCR53C8XX driver.
Please read drivers/scsi/README.ncr53c8xx for more information.
If you want to compile the driver as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read Documentation/modules.txt. The module will be called sym53c8xx.o.
