Hi,
this little patch prints the SCSI-ID of an AHA154xX (at least it does
with my AHA1542B, when I played with the SCSI-ID jumpers). The info
is from the AHA154x-Manual from the adaptec-ftp-site.
Though I thought you could verify if it prints valid values with other
boards before including in the kernel.
Sincerly, Gunther (gmayer@physik.uni-kl.de)
