Accompanying drawing explanation
Accompanying drawing 1 is the flowchart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the invention will be further described.
As shown in Figure 1, a kind of method improving BIOS Legacy Option ROM Space utilization rate, by improving the execution sequence of existing Option ROM, it is effectively improved the space availability ratio of Option ROM.
It realizes process:
Server powers on start, and after BIOS initialization completes CPU, internal memory etc., when initializing extrapolation equipment, the preferential Legacy Option ROM performing all network interface cards, other cards call execution according to PCI scanning sequency.
When running into the situation because Oprom ROM Space is not enough in execution, according to the equipment arrived and its Legacy Option ROM size of scanning, optimizing and revising execution sequence, put flag bit, system is Reset.
Particularly as follows:
Server system BIOS arranges control module；
Server powers on, and after starting up, BIOS starts execution and its control module is started working；
BIOS initialization extrapolation equipment, its initialization procedure is, first initializes the Legacy Option ROM of all network interface cards, and then other card calls execution according to PCI scanning sequency, i.e. according to the Option ROM Space size of the equipment scanned to call execution.
When running into the situation of Oprom ROM Space deficiency in performing, according to the equipment scanned and its Legacy Option ROM size, optimize and revise execution sequence, and flag bit is set, after system reboot, perform according to the order after adjusting.
Described execution sequence of optimizing and revising refers to preferentially perform the big equipment of Option Rom, when Option Rom space size is identical, and the limited enforcement Option Rom size equipment much larger than RuntimeCode.
Instantiation:
Due to Option ROM size with the size of RuntimeCode be different, the Option ROM size of such as Raid card 2108 is 0xA000 byte, and Runtime Code size is 0x6800 byte；The Option ROM size of ten thousand Broadcom 82599ES is 0x11E00 byte, and RuntimeCode is 0x1000 byte；When remaining space is 0x12000, execution sequence divides the following two kinds situation:
(1) first carrying out 2108,0x12000 > 0xA000, can perform, after execution, remaining space is 0x12000-0x6800=0xB800, and remaining space cannot perform less than the network interface card Option ROM of 0x11E00,82599ES, causes the functional faults such as network interface card PXE.
(2) 82599ES is first carried out, 0x12000 > 0x11E00, can perform, after execution, remaining space is 0x12000-0x1000=0x11000, and remaining space can perform more than 0xA000, the Option ROM of 2108.
The situation that execution sequence is (1) above of BIOS acquiescence, i.e. the Option ROM of network interface card finally performs, and this will result in the functional fault of system, and this fault is avoidable, i.e. performs according to the order of (2).Single channel server product is commonly equipped with 2-5 PCIE slot at present, and two-way is exactly more than 6, it is easy to the situation that Option ROM Space is not enough occur.By adjusting execution sequence, preferential execution Option Rom is big, and especially its Option Rom size equipment much larger than RuntimeCode, can be greatly improved space availability ratio.
