Description bmacy 1998-11-23 12:57:31 UTC
The aic7xxx driver defaults to EXTEND_TRANS_[AB] being
enabled if a seeprom is not found. This causes a disk
partitioning scheme made with the v5.0.19 driver (shipped
with RedHat 5.1) to be invalid after an upgrade. This can
no be fixed using command-line args to the driver or any
BIOS settings. I got around it by making it default like
the driver I originally installed with. I can't see why
there is a valid reason to force Linux to use Translation
when it doesn't need it. Anyways, basically Redhat is
screwed now since they shipped a product that defaults the
other way... there is no way to make everyone happy.
Someone should add a "noextend" parameter for the driver.

I can confirm. It was introduced in 2.0.36pre14. The driver should
really be made to read the BIOS setting again.
I have reported it on 11 Nov 1998 on linux-kernel@vger..., as well as
to Alan and Doug.

Doug, do you have anything to say about this one?

Comment 3 motyl 1998-11-25 20:48:59 UTC
Easy way of getting system to boot again:
Having disk partitioned without extended translation, LILO install
in 2.0.36 kernel results in unbootable system.
But after enabling extended translation in BIOS the system boots
(fdisk is still confused though).
