Log Message:
First cut at x68k network bootloader via NE2000 on Neptune-X and Nereid.
Written by isaki@ back in 2003 based on x86's NE2000 netboot, and
misc debug and improvements by tsutsui@ and Y.Sugahara.
Tested on XM6i (emulating Nereid Ethernet) and X68030 + Neptune-X by me,
also on X68030 + Nereid and X68000 PRO-II + Xellent30 + Nereid by isaki@.
Note:
- X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid,
so this network bootloader needs to be loaded from floppy or harddisk.
- Currently netboot support is not merged into the secondary Multi-boot
(/usr/mdec/boot) due to size restriction.
- Primary loaders assumes that the secondary bootloader name is /boot,
so /usr/mdec/netboot needs to be installed as /boot into the target
bootstrap device.
