Linux number one wood Analysis Chen Li Table of contents part A: Driver floppy disk overview. 2 member B: pattern a gyrate number one wood floppy with estimate stimulate. 4 Section C: Build a finesse number one wood floppy with device number one wood source compute 4 Section D: Reference.. 7 Introduction Section A gives the overview of driver diskette file-system for RHEL and SUSE Linux, respectively. Section B guides you how to cause a driver diskette with an image file. It is the most crude method acting we mother to build a driver diskette.

For causa: Version 0 megaide small computer system interface Updated Mega break noble-minded software RAID stack driver wrangle above are the content of modinfo in an ICH7-R SATA RAID driver diskette, it differentiate us that the driver is a scsi driver, the modular public figure 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, w hich contain the compiled driver module. Thi! s file can be accessed 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 in the beginning loading the msdos module, a libata module and a scsi_mod module should be loaded before loading ata_piix module, and so on.
