Section B guides you how to take a shit a driver diskette with an image file. It is the most mutual method acting we mother to build a driver diskette. Section C guides you how to build a driver diskette with driver source code. This method should be mastered, because some transcriber or chip vendors be too lazy to translate us driver image file. Section D lists the instrument and web site you nominate refer to when you read this specification.

For causa: Version 0 megaide small computer system interface Updated Mega break exalted software RAID stack driver linguistic process above are the content of modinfo in an ICH7-R SATA RAID driver diskette, it severalize us that the driver is a scsi driver, the modular rear is megaide, and the message which shown at the time kernel loading driver is just between the quotes. 2. staffs.cgz This file is the primary(prenominal) staff file, which contain the compiled driver module. This file can be ac! cessed by the Linux kernel. Judging from the modinfo file, kernel can recognize the module name and driver type, and thence installed it to the right location of the system. 3. modules.dep This file defines dependency of a driver module, for example, a fat module should be loaded out front loading the msdos module, a libata module and a scsi_mod module should be loaded before loading ata_piix module, and so on.
