 +===== Deliverables and Timeline =====
 +
 +Note: Since I am working with Etherboot 5.4.x, I am going directly for 16:32 UNDI stack support. As of 7/30, the UNDI driver works with the NE2K-PCI, which uses PIO to send data to/from the card. 
 +
 +  * Test on alternate Etherboot hardware, including real hardware
 +  ** Test card that uses PIO to set up DMA
 +  ** Test card that uses memory mapped registers to set up DMA
 +  * Test with full network boot (LTSP, NFS root)
 +
 +  * Experiment with getting other other PXE stacks -- inference of segment lengths via E820 holes.
 +
 +These steps are done
 +
 +  * Implement memory map functionality for Linux
 +  * Set up UNDI Probe memory map
 +  * Find UNDI ROM
 +  * Make sure E820 Map is sane [[E820IRC:​IRC Logs for E820 issue]]. I am Here (6/​15/​2006). Estimated completion time 6/20/2006
 +  * Hard code segment descriptor & location. 16:32 downcall (est 6/27/2006)
 +  * Test UNDI calls, see proposal for details (est 7/4/2006)
 +  * Integration with TUN/TAP device; transmit data with Linux (est 7/11/2006)
 +  * PXE Extensions for segment descriptor & location
 +  * Interrupt processing cleanup (est 7/18/2006)
