  Hello,

I tried to boot netbsd on C200, but it fails like this:

>> NetBSD/hp700 LIF/FFS/LFS Boot, Revision 1.2
>> (itohy@pino.my.domain, Tue Nov 11 23:06:25 JST 2003)
>> Enter "reset" to reset system.
Boot: [[[lf0a:]netbsd][-a][-c][-d][-s][-v][-q]] :-
pdc_finddev(-1, 1002)
IODC_READ: -6
open lf0a:netbsd: Device not configured
boot: Device not configured
Boot: [[[lf0a:]netbsd.gz][-a][-c][-d][-s][-v][-q]] :- 

(Note some of the debug options are enabled.)

The error code -6 means the buffer size is too short.
I bumped the buffer size from 16KB to 32KB (patch attached)
and it works:

SPID bits: 0x0, error = -2
WARNING: no HPT support, fine!
panic: no kernel support for PA8200

(The kernel doesn't work, however. :)

Is this change correct?
(C180 doesn't require this change, FYI.)
