PXE boot

[Sinha, Prokash]

Hi All,

I'm trying to understand the invocation of the routines pxe_init(); pxe_open()   etc.  in pxe.c

By the structure, it looks like a driver with devsw_pxedisk = { entry points …}

Once this pxeldr is brought down from the net boot server, how does it get invoked ( or rather who calls these routines ) ??? The loader ( strapped with it don't seem to call).

I assume that the the boot code in the NVRAM ( or wherever ) of the NIC that supports calls these pxe_* () functions ???

Thanks
