Hi Peter, I traced over these routines you suggested briefly and I didn't see where it invokes PXE UNDI_API (PXENV_UNDI_SHUTDOWN(0x5) to shut down the device. When this is invoked, my UNDI driver will put the device into an inactive state so that it doesn't do any more DMA read/write over PCIe bus anymore. What am I missing? Thanks!

...running PXELINUX on top of Etherboot? There is something in Etherboot 5.1.7 called FREEBSD_PXEEMU, which seems to be a PXE stack subset, in particular it seems to support the following calls: PXENV_GET_CACHED_INFO PXENV_UDP_OPEN PXENV_UDP_WRITE PXENV_UDP_READ PXENV_UDP_CLOSE PXENV_UNLOAD_STACK PXENV_UNDI_SHUTDOWN This happens to be pretty close to the subset used by PXELINUX, with two exceptions: PXELINUX will also invoke PXENV_STOP_UNDI (for version >= 2.00) or PXENV_UNDI_CLEANUP (for version < 2.00). I'd be really curious to see how this would play out. There are of course also other kinds...

Hi Peter, They use PXELINUX to download the OS deployment bootstrap. When this is completed, they want to shutdown the stack including the UNDI driver before jumping to the kernel. Thanks!
