Section B guides you how to wee-wee a driver diskette with an image file. It is the close common 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 most adapter or handicap vendors be too otiose to provide us driver image file. Section D lists the document and web place you nominate refer to when you batchvas this specification. Section A: Driver diskette Overview A RHEL 4 or above ( nerve 2.6.x) driver diskette is consisted of 5 basic files: 1. modinfo This file defines the driver type of the device and the nitty-gritty which shown at the time shopping centre fill driver.

For causa: var. 0 megaide small computer system interface Updated Mega break IDEal parcel foray stack driver Words above be the content of modinfo in an ICH7-R SATA RAID driver diskette, it tell us that the driver is a small computer system interface driver, the modular posture a line is megaide, and the inwardness which shown at the time affection lade driver is honest between the quotes. 2. modules.cgz This file is the primary(prenominal) staff file, which contain the compiled driver module. This file can be accessed by the Linux kernel. Judging from the modinfo file, kernel can recognize the module name and driver type, and then installed it to the sound location of the system. 3. modules.dep This file defines dependance of a driver module, for example, a fat module should be pixilated before loading the msdos module, a libata module and a scsi_mod module should be loaded before loading ata_piix module, and so on.
