: I am attempting to compile a new v1.1.18 kernel using cyril's v1.2 DPT SCSI
: drivers. Unfortunately, the dpt.h header file includes a "standard" header
: file called scsicam.h (the entry is #include <linux/scsicam.h>) That header
: file is not included in my Slackware 2.0.0 distribution from Walnut Creek (on
: CD-ROM). I checked the source for v1.0.9 and it isn't there either. Can
: anyone point me to the correct file? Thanks a bunch.
The file is found, under newer kernels, in directory/file
/usr/src/linux/include/linux/scsicam.h
Here is the most recent copy of the README I include with the boot
disk I uploaded to SUNSITE. Following the standard directions
for Cyril's patch at 1.1.45 and my caveat for later kernels this
works all the way up to 1.1.58.
Good luck,
Steve...
---------
SLACKWARE 2.0.0 1.44 Meg BOOT DISK FOR DPT CONTROLLERS (ALPHA!!!)
(NOTE: There are two different drivers for DPT out there...one
in the SCSI HOWTO has a file dpt.c, which is used here. There is
another one under development called eata.c, also available from
the MIT site for which there is a different set of disks available
at sunsite and funet I think.)
The file 'dptscsi.gz' is a Slackware 2.0.0 boot disk, with a version
1.1.54 of the kernel with DPT SCSI and limited NET installed. It
was used successfully with a DTP 2122 EISA controller on DEC 1.05
and 2.10 Gig drives. I personally did the install of the basic
system and the network files, then FTP-ed the rest of Slackware
to the box and continued the install. I used the 3C509 (3C579
actually) card, and NE2000 is in there too.
Make sure you get the latest patches from the source listed in the
SCSI HOWTO. Don't forget the README for patching kernels...lots of
people forget the -p0 parameter to patch! If the DPT patches are
against 1.1.45, then you will have to make changes to advance to the
newer kernels. After kernel 1.1.48 or .49 a change needs to be made
to the dpt.c file under /usr/src/linux/drivers/scsi to give an
additional parameter to the dma_request routine. I kludged it myself
by replacing the line
if(request_dma(dma_trans[ccb_info.drqx])) {
with
if(request_dma(dma_trans[ccb_info.drqx],"dptEATA")) {
and it worked fine (up to 1.1.53 at least).
Remember, until you compile the new kernel you will have a little
problem booting your installed system, as DPT is still ALPHA and
not included with the system distribution. To reboot your box after
the initial installation, you can use the boot disk and at the LILO
prompt use the line
mount root=/dev/sda1
/\ or whatever your partition is
to get the machine going. Also, the larger SCSI drives will exceed
LILO's ability to boot directly. Currently, I boot from floppy but
shortly I plan to install a small, fast drive that I will boot from
and that will also contain my SWAP partition to help balance the load.
If you need a kernel, you could mount the floppy '-t minix' and copy
the kernel...it is set to boot the root partition as /dev/sda1.
Good luck!
Steve...
