Interesting. Well, the fileserver code is rather behind the cpu code
for this controller. Perhaps jmk's rumoured fileserver hacks to allow
driver sharing will help here.

In the meantime, you may enable diagnostics in scsincr53c8xx.c:

/*******************************/
/* Fileserver specific defines */
/*******************************/
#ifdef FS
#define xalloc(n) ialloc(n, 1)
#define KADDR(a) ((void*)((ulong)(a)|KZERO))

#define KPRINT if(1)print
#define IPRINT if(1)print
#define DEBUG(n) ((n) <= 2)
#define IFLUSH()
#endif

This will produce a lot of output. Perhaps it should be caught
using a uart console....

It will certainly give more clues.

Hello,

I am installing 9fs. The target is as bellow:
MB: ASUS SP97-V
cpu: K6/233
ether: 3C905b
scsi card: SYM53C895
scsi #0: IBM DNES-309170LV (9GB Ultra2 SCSI)

This mother board lead me "config:" message of 9pcfs.
However SCSI is something weird.
The messages are as follows:

ether#0: elnk3: port 0xB800 irq=9: ....
sd53c8xx: SYM53C895 rev. 0x01 intr+10 command=2000017
found 9PCFS ...
...
scsi#0: 53c895: port 0 Failed to INIT controller
...
config: ...
...
config: ream main
config: end
sysinit
devinit w0
stack trace of 1
1048 stack out of 4000
...
panic: scsiio: device : w0


I could format the disk using scsi configuration menu
that is shown before FD is accessed.

Any ideas are welcome.
