SYSLINUX API call INT 22h/AX=0xC
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!
Kevin

SYSLINUX API call INT 22h/AX=0xC
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!
Kevin
