To install LAN8710A for BeagleBone under MINIX you have to edit /etc/inet.conf To install LAN8710A for BeagleBone under MINIX you execute 'netconf' as
by adding line: usual. Select the LAN8710A driver from the list. Restart the system
eth0 lan8710a 0 { default; }; and the driver should work.
and changing:
psip0 { default; };
to:
psip1;
Restart the system and the driver should work.
