Computer system and device driver installation method

摘要

A computer system includes: storing a first file management table that stores a record associating a device driver that can be installed in the computer system with identification information of a logic area in which the particular device driver is stored; reading a second file management table stored in a recording medium placed in the drive, generating a third table by inserting the record in the first management table into the second management table, and generating a virtual file management table that associates the third table with the device driver stored in the first table as well as the device driver stored in the second table, and searching for the device driver requested, install the requested device driver.

1. A device driver installation method performed by a computer system connected to a drive for reading a recording medium,
wherein the recording medium stores an OS installer, in-box device drivers to be requested by the OS installer, and a recording medium file management table which stores relationships between the in-box device drivers and identification information of logic areas in which the in-box device drivers are stored, wherein the computer system comprises
a server blade including a CPU, main storage unit, and a base management controller (BMC); anda service processor (SVP) storing out-box device drivers that are not the in-box device drivers, and a SVP file management table which stores relationships between the out-box device drivers and the identification information of logic areas in which the in-box device drivers are stored, the device driver installation method comprising:
reading, by the CPU, the OS installer stored in the recording medium into the main storage unit;copying, by the BMC, the recording medium file management table in the recording medium and the SVP file management table in the SVP into the BMC, before reading the OS installer;generating, by the BMC, a third table by inserting a record of the out-box device drivers stored in the copied SVP file management table into the copied recording medium file management table, before reading the OS installer;assigning new identification information of logic areas to the out-box device drivers so that the identification information of logic areas for the out-box device drivers and the identification information of logic areas for the in-box device drivers are unique to each other;generating, by the BMC, a virtual file management table in the BMC, by connecting information of the copied SVP file management table and the copied recording medium file management table to the third table, before reading the OS installer;searching, by the CPU reading the OS installer in the main storage unit, for a device driver requested by OS installation to the server blade, using the virtual file management table in the BMC; andinstalling, by the CPU, the requested device driver from the recording medium and the SVP; wherein the recording medium file management table, the SVP file management table, the third table, and the virtual file management table are distinct tables.
