Hello,
I need to explain the San boot sequence(procedure) & compare it to the boot
from a local HDD.
with a local HDD it goes this way: Power Good > POST > secondary BIOSs >OS boot
from HDD.
With a local (physical) hard drive connected to the HDD controller (ATA/SCSI)
it's the BIOS that accesses the HDD before the OS's HDD driver is loaded, but
how about AoE SAN boot ?
I know that before gPXE quits it registers the SAN target (AoE or iSCSI) as a
BIOS drive, what does that really mean ? How does the BIOS know how (the
protocol) to access the BIOS drive over AoE ? Where is the driver responsible
for this step ?
I might be completely wrong or missing an important part of the process so,
please, be kind & explain me what is happening in the background.
Thanks !
TheMadOne.
