The recent update of aic7xxx in 2.0.36 kernel (pre13-pre14 transition) made
"extended translation ENABLED" the default setting, independed of the BIOS
setting (which was the default before). It breaks fdisk and LILO on SCSI
disks formatted with extended translation disabled (see examples on
http://crds.chemie.unibas.ch/machine/2.0.36pre19/ )
I would like to ask if there is any way of switching off extended translation
in Adaptec AIC7xxx driver version 5.1.3/3.2.4 ? If the source code
modification is the only way, what would be the first place to add it?
How hard would it be to make aic7xxx driver to read default value of this
parameter from BIOS again ?
Please CC any replies to motyl@stan.chemie.unibas.ch

P.S. To test: boot new kernel, run fdisk on your SCSI disk, display
partition table. If you had used extended translation before, you won :-)
