5.6.33IBA Capabilities (Word 33h)

Word 33h is used to enumerate the boot technologies that have been programmed into the FLASH. It is updated by IBA configuration tools and is not updated or read by IBA.

Table 5-18. IBA Capabilities

Bit	Name		Description

15:14	SIG	Signature. These bits must be set to 1b to indicate that this word has
15:14	SIG	been programmed by the agent or other configuration software.


13:5	Reserved	Reserved for future use. Set these bits to 0b.

		SAN capability is present in FLASH.
4	SAN	0b	= The SAN capability is not present (default).
		1b	= The SAN capability is present.

		EFI UNDI capability is present in FLASH.
3	EFI	0b	= The RPL code is not present (default).
		1b	= The RPL code is present.

		RPL capability is present in FLASH.
2	RPL	1b	= The RPL code is present (default).
		0b	= The RPL code is not present.

		PXE/UNDI capability is present in FLASH.
1	UNDI	1b	= The PXE base code is present (default).
		0b	= The PXE base code is not present.

		PXE base code is present in FLASH.
0	BC	0b	= The PXE base code is present (default).
		1b	= The PXE base code is not present.

5.6.34IBA Secondary Port Configuration (Words 34h-35h)

These words provide a unique configuration for the second port of the 82546GB/EB. The format is the same as that used in words 30h and 31h for LAN A.
