Eric, thanks for your help. Its 2.6.16.36 on Debian Sarge, using most recent 
kernel version is not always a good idea on server systems - too many 
regressions. 
Attached is dmesg output from 2.6.19.1.

Sure, its enabled now.

Until Monday I don't have physical access to the machine, so an update from 
DOS is not possible now. However, I see there is also a linux mptflash, I 
just can't get it compiled.

gcc -g -O -Wall -I..   -c -o mptflash.o mptflash.c
In file included from ../mptbase.h:58,
                 from mptflash.c:13:
../linux_compat.h:9:30: error: scsi/scsi_device.h: No such file or directory
../linux_compat.h:10:28: error: scsi/scsi_cmnd.h: No such file or directory

The kernel_headers in Debian don't have these files and including the header 
files directly from the kernel tree doesn't work. 
Do you have newer sources (the most recent version I could find are from 
mptlinux-3.02.60) or a working binary?


Thanks,
Bernd
