I have 5 machines that are linux only, and just the one
that is Windows. Been using it to test setup of my G4L
project for regular usb boot using grub4dos, and UEFI
boot using grub2. Both work fine, but the issue is
windows puts the nic in some state when it does a warm
restart that messages the dhcpc setup from the linux
client. Added the following line to the script that does the
dhcpc setup.
echo 1 > $(find /sys | grep $(lspci | grep -i ethernet | cut -f1 -d\ ) |grep reset)
finds the pci device for the ethernet, and then sets the
reset to 1
That seems to handle the process of fixing what windows
breaks.. Will have to look at modifying it to handle
systems that might have more than 1 ethernet device?
Thanks for the reply.
