Problem: lost hardware interrupt messages with Novell/Anthem NE2100
ethernet card and Netware 386 V3.10 Rev.A on a server with 486 CPU. When
loading patches about 5 to 10 lost hardware interrupt messages occur
between each patch. The problem shows up even when the server is idle
and when no workstation is connected (ca. 3 alerts per minute). Loading
modules streams, clib and mathlib results in a constant display of such
messages and continous beeping from the internal speaker.

The device removing the interrupt request before the PIC can set the IRQ
vector for the CPU is clearly the ethernet board, because the system
works perfectly when the NE2100 is replaced by an NE1000 (identical
settings, except DMA). Adding one wait state with a jumper on the NE2100
makes no difference.

Also switching off the display message with set ... command is no
solution. The server's performance is too much impaired.

Below16.dsk loaded before ne2100; driver from LAN_DRV_111 disk; I/O=340,
INT=5, DMA=7, frame=ethernet_802.3.

All suggestions welcome.
