I have an Acer Power machine with a built in Adaptec AIC 7850 SCSI controller.
Will Linux recognise this controller, or does it need external drivers?

The 2940 *is* supported, but the driver is not stable for all

We recently purchased an ASUS Pentium with an Adaptec PCI-2940 adapter
on-board. This computer will run linux 1.2.13 and I have configured a kernel
with the AIC patch reverse engineered from the 1.3.x version. Retrieved from
ftp.teleport.com. None of the patches or images for prior kernels worked
either, the June 1.2.10 or the November 1.2.10 patches
My kernel detects (not quite -- described later) and partions the disk ok
but when I try to format the hard drive with mke2fs the system spews the
following message forever (8 hrs).
aic7xxx: Warning - No command for SCB 0 (CMDCMPLT)
QOUTCNT(1) SCB state(0x0) cmd(0x0 pos(0)
On boot there are a couple of questionable messages which appear, first:
aic7xxx: Reading SEEPROM...aic7xxx: Unable to read SEEPROM
aic7xxx: Using 3 SCB'S; No SCB memory check
Please excuse any mis-types on the system messages as I typed them by hand
and didn't get them from the screen.
I have tried disabling the sync negotiation, disconnection/reconnection and
changed the DMA transfer rate from 10.0 to 5.0. Also I tried the enable option
and turned off support for the disk >1024 cyl. even though these option don't
apply to my 500m drive.
The numbers of the on-board chip read as follows:
If anyone can shed some light on this problem please send me some Email.
Thanks in advance for any efforts on my behalf!
