But your system has a subordinate PCI BUS (#1) on which your 896 is
installed and such a RAID option is hopefully available.

There are plenty of these boards that run Linux, probably.
I have no idea about the cause that precludes 2.2.10/11 from booting on
your system. What I may recommend you is to make the simplest possible
kernel and to try to boot it. Only configure required options. The
SYM53C8XX driver should be fine under 2.2.10/11, so only configure this
one and not both NCR53C8XX and SYM53C8XX. Remove complex things as RAID,
module support and donnot configure drivers and options that are not
absolutely needed.

PS: If you just want to look at the kernel init phase, you just have to
provide root FS that does not exist at boot.
