We are attempting to run RTLinux on a couple motherboards that do not use the
Intel 440BX chipset, but
instead have only "legacy" ISA support in the chipset. We can't get the sound
example to execute on an
AMD K6 motherboard with the ALi PCI to ISA Bridge M1533, Host Bridge M1541,
PCI Bridge M5243 identifiers in the /proc/pci output. This MB hangs waiting for
an interrupt to be generated by the fifo when
the linux.au file is cat'ed to /dev/rtf3.

The second MB is a Cyrix GMx and CS5530. On this system after rtl_time and
rtl_sched are insmod'ed, the
Linux system date stops updating (it runs at about 1/120) of real-time.

Any help on identifing the problems would be greatly appreciated.

TIA.
Cliff King
