Abstract

An information handling system downloads device drivers for recovery operation of the information handling system, and subsequently obtains first configuration information associated with each of the device drivers. The system performs an inventory of devices associated with the information handling system that includes obtaining second configuration information associated with each of the devices in the inventory, and compares the first configuration information and the second configuration information. If the particular device driver is missing, then the system downloads the particular device driver prior to boot to a service operating system.

Claims20

Dependent claims

A method for handling instructions in a pre-boot execution environment of an information handling system, the method comprising:

in response to a boot failure, performing operations, by a processor, that include:
creating a random access memory disk storage space by allocating a portion of a random access memory in the pre-boot execution environment for storage of a plurality of device drivers for recovery operation of the information handling system;
downloading and storing in the random access memory disk storage space of the portion of the random access memory, the device drivers for the recovery operation of the information handling system;
generating a first configuration information based on the device drivers that were downloaded and stored in the random access memory disk storage space;
performing a device scan to obtain an inventory of current device drivers of the information handling system, wherein the inventory includes a second configuration information associated with each of the current device drivers in the inventory;
comparing the first configuration information and the second configuration information to determine if there is a discrepancy between the first configuration information and the second configuration information;
in response to determining there is a missing device driver based on the discrepancy and the missing device driver is available for download, downloading the missing device driver prior to booting to a service operating system;
and
in response to determining there is a missing device driver based on the discrepancy and the missing device drive is not available for download, generating a message regarding the missing device driver and transmitting the message to a manufacturer of the information handling system, wherein the message includes an impact to the recovery operation of the information handling system.

An information handling system, comprising:

a pre-boot execution environment;
and
a processor coupled to the pre-boot execution environment, the processor configured to:
in response to a boot failure, create a random access memory disk storage space by allocating a portion of a random access memory in the pre-boot execution environment for storage of a plurality of device drivers for recovery operation of the information handling system;
download and store in the random access memory disk storage space of the portion of the random access memory, the device drivers for the recovery operation of the information handling system, wherein the device drivers are based on components of the information handling system at time of purchase of the information handling system;
subsequent to the download and the store of the device drivers, obtain a first inventory of device drivers stored in the random access memory disk storage space, wherein the first inventory includes a first configuration information associated with each of the device drivers;
perform a device scan to obtain a second inventory of current device drivers of the information handling system that includes obtaining a second configuration information associated with each of the device drivers in the second inventory;
compare the first configuration information and the second configuration information;
determine whether a particular device driver is missing based on the comparison of the first configuration information and the second configuration information;
in response to a determination the particular device driver is missing, and the particular missing device driver is available for download, download the particular device driver prior to boot to a service operating system;
and
in response to a determination the particular device driver is missing and the particular missing device driver is not available for download, generate a message regarding the missing device driver and transmit the message to a manufacturer of the information handling system, wherein the message includes an impact to the recovery operation of the information handling system.

A non-transitory computer readable medium storing instructions that when executed cause a processor to:

in response to a boot failure, performing operations that include:
creating a random access memory disk storage space by allocating a portion of a random access memory for storage of a plurality of device drivers for recovery operation of an information handling system;
downloading and storing the device drivers for recovery of the information handling system in the random access memory disk storage space, wherein the device drivers are based on components of the information handling system at time of purchase of the information handling system;
subsequent to the downloading and the storing of the device drivers, obtaining a first inventory of device drivers stored in the random access memory disk storage space, wherein the first inventory includes a first configuration information;
performing a device scan to obtain a second inventory of current device drivers of the information handling system that includes obtaining a second configuration information of the current device drivers in the second inventory;
comparing the first configuration information with the second configuration information;
in response to determining a particular device driver is missing based on the comparison of the first configuration information and the second configuration information and the particular missing device driver is available for download, downloading the missing device driver prior to boot to a service operating system;
and
in response to determining the particular device driver is missing and the particular missing device driver is not available for download, generating a message regarding the missing device driver and transmitting the message to a manufacturer of the information handling system, wherein the message includes an impact to the recovery operation of the information handling system.
