ABLE has drivers for a common set of Ethernet adaptors encompasing those found on Simtec Electronics boards and common PCI cards. The supported cards include those based upon Davicom DM9000 chipset, Tulip chipset, Realtek chipset and the traditional NE2000 based devices. ABLE does not currently have support for serial based protocols such as Serial Line Internet Protocol (SLIP) or Point to Point Protocol (PPP) but there is provision for XModem protocol (see Section 6.4, “XModem source”)
To transfer files ABLE uses the Trivial File Transfer Protocol (TFTP) protocol. TFTP is a very simple protocol it lacks the ability to list directory contents, has no authentication or encryption mechanisms and performs its transfers in lock-step with only one packet on the network at any time which reduces its performance. Despite its lack of facilitys it is sufficient for retreving files.
