        I just installed the Redhat's Linux 1.2.8 release on a Gateway 200
Pentium 120 (Triton chipset).  PCI boards included an STB Trio64 video card,
a Buslogic 946C SCSI controller, and an SMC EtherPower adapter.  I recompiled
the RH 1.2.8 kernel with PCI BIOS support and Donald Becker's DEC 21040
driver for the EtherPower board.
	When I tried to ifconfig eth0 up, I received the following error:

SIOCSFFLAGS: Try Again

which the Ethernet-HOWTO explains as, "Some other device has taken the
IRQ that your ethercard is trying to use, and so the ethercard can't
use the IRQ."  Looking at /proc/interrupts, and comparing with
ifconfig eth0, I discovered that both the Buslogic SCSI controller and
the Ethernet adapter were assigned to IRQ 9.
        Isn't PCI plug-and-play supposed to assign different IRQ's to
different boards?  Any suggestions?
