EIP 16566. Order of legacy devices within BBS group is reset +// when configuration changes. +// Symptoms: Order of legacy devices within BBS group is sometimes reset +// when bootable devices are added (enabled) or removed (disabled). +// Here is one of the ways to reproduce the problem: +// 1. Make sure the following bootable devices are plugged into the +// system: +// - Bootable network device (onboard or offboard) +// - USB flash drive emulated as hard drive +// - IDE or SATA hard drive +// 2. Boot to setup. +// 3. Enable PXE boot using "Lunch PXE OpRom" option on the "Advanced" +// page. +// 4. Save the settings, reboot the system, and enter the setup. +// 5. On the "Boot" page, update "Hard Driver BBS Priorities" to set USB +// drive as a first boot device. +// 6. Disable PXE boot using "Lunch PXE OpRom" option on the "Advanced" +// page. +// 7. Save the settings, reboot the system, and enter the setup. +// 8. Enter "Hard Driver BBS Priorities" menu on the "Boot" page. +// USB drive priority has been reset( it is no longer the first boot +// device). +// Details: BDS used index within BBS table to match saved priorities with +// available boot devices. +// However, when list of boot devices changes, BBS index may also change. +// For example, when network boot is enabled, boot option for a network +// device +// is inserted into the BBS table prior to the USB drive boot option. +// As a result, index of the USB drive boot option increases by one +// and matching against saved boor priority fails. +// BDS code is updated to save more information about legacy boot devices. +// For every legacy boot device BDS saves +// checksum of the device name into the NVRAM (along with device index). +// When index matching fails, BDS uses saved checksum to find updated BBS +// index +// of the boot option. +// +// 79 1/14/09 3:52p Felixp +// BDS updated to signal beginning of the driver connection cycle by +// installing the protocol. +// +// 78 1/05/09 3:02p Felixp +// Bug fix.

The SOR, Before, and After Depex are + pre-processed as drivers are added to the mDiscoveredList. If an Apriori + file exists in the FV those drivers are addeded to the + mScheduledQueue. The mFvHandleList is used to make sure a + FV is only processed once. + + Step #2 - Dispatch. Remove driver from the mScheduledQueue and load and + start it. After mScheduledQueue is drained check the + mDiscoveredList to see if any item has a Depex that is ready to + be placed on the mScheduledQueue. + + Step #3 - Adding to the mScheduledQueue requires that you process Before + and After dependencies. This is done recursively as the call to add + to the mScheduledQueue checks for Before and recursively adds + all Befores. It then addes the item that was passed in and then + processess the After dependecies by recursively calling the routine. + + Dispatcher Rules: + The rules for the dispatcher are in chapter 10 of the DXE CIS.
