Adaptec AHA274x. No BIOS32 extensions present.

I can't seem to get Linux to boot up on a P60 with the Adaptec AHA274x SCSI
adaotor.  It seems to recognize the adaptor on autoprobe but I get the

aha274x: warning: ignoring channel B of 274x-twin
aha274x: extended translation disabled
        irq 11
        bus release time 60 bclks
        data fifo threshold 100%
                scsi id 7
                scsi bus parity check enabled
                scsi selection timeout 256 ms
                scsi bus reset at power-on enabled
                scsi bus termination disabled
No BIOS32 extensions present. This release still depends on it.  Sorry.
scsi0 : Adaptec AHA274x/284x (EISAZ/VL-bus -> Fast SCSI) 1.28/1.11/1.29
scsi : 1 host.
scsi : aborting command due to timeout : pid 0, scsi0, id 0, lun 0 0x00 00 00 00 00 00

I've used the EISA config utility to enable the BIOS.  When the machine resets
it prints the message BIOS installed after it displays information in the
SCSI board.  Do I need a BIOS upgrade for the host adaptor?

Thnaks in advance,

Hello everybody,

I have problems with the installation of Linux on my Valuepoint.
Does anybody know what the following message means?

   No BIOS32 extensions present. This version still depends on it.

Afterwards the hard disk can not be found. I do not know if both
problems are correlated. Can anybody tell me what this error means
and/or how to fix it?
