[Etherboot-developers] Problems with Multiboot BIOS and Etherboot ....

[Christoph P. <chr...@gm...>]

Integrating Etherboot to a Phoenix BIOS of an embedded Pentium
board make some problems. See Email below.

Further we have following problem:
The board has 3 ethernet chips (82559ER). Now the Etherboot image
using "NO_DELAYED_INT" starts 3 times (booting "L"ocal after
3 seconds), then it writes "No SYSTEM found, press any key",
after a ENTER, the BIOS boots normally.

How can the Extension be integrated (with the constraints descirbed
	below).

How can Etherboot be built, that the ROM boot loades is activaed
and the PCI devices are found, but WITHOUT beeing a BBS compliant
image (not comming in the boot order of boot devices) ?

I hope, anybody can help here !

With friendly regards
