4.5.1.29.6 Configuration Customization Options PCI Function 1 (Word 35h)
This word is the same as word 31h, but for function 1 of the device.
4.5.1.29.7 iSCSI Option ROM Version (Word 36h)
Word 0x36 of the NVM is used to store the version of iSCSI Option ROM updated as the same format as
PXE Version at Word 0x32. The value must be above 0x2000 and the value below (word 0x1FFF = 16
KB NVM size) is reserved. iSCSIUtl, FLAUtil, DMiX update iSCSI Option ROM version if the value is
above 0x2000, 0x0000, or 0xFFFF. The value (0x0040 - 0x1FFF) should be kept and not be overwritten.
