i recompiled my kernel with scsi emulation built in

i also compiled with scsi cdrom support and generic scsi support, i'm using devfs

i still get this error:

did you include the required /dev/hda=ide-scsi in your /boot/grub/menu.lst?

did you not see the line?

rommel · Posted: Fri Jul 19, 2002 8:51 pm Post subject:

you dont use /dev/hd?, just hd?=scsi

atleast thats what i have and it works

default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux
root (hd0,0)
kernel /boot/bzImage root=/dev/md0 hdc=scsi vga=788

title=backup
root (hd0,0)
kernel /boot/bzImage.old root=/dev/md0 hdc=scsi vga=788

hi,
i had the same problem, but finally it's really easy to solve.
there must be several things compiled into the kernel or build as a module:

atapi / ide / mfm / rll support menu
o disable ide / atapi cdrom support
o enable scsi emulation support

scsi support menu
o enable scsi cd-rom support
o enable scsi generic support

there's no need of adding 'hd*=ide-scsi' in lilo / grub.

after rebooting there's sth like 'scsi0 : SCSI host adapter emulation for IDE ATAPI devices' in your dmesg.

last step: change your devfsd config. here's an example (my config)

- - %< - - - - - - - - - - %< - - - - - - - - - - %< - - - - - - - - - - %< - - - - - - - - - - %< - -
# Give the cdrw group write permissions to /dev/sg0
# This is done to have non root user use the burner (scan the scsi bus)
REGISTER ^sg0$ PERMISSIONS root.cdrw 660

# Create /dev/dvd for the second cdrom drive
# (change 'cdroms/cdrom1' to suite your setup)
LOOKUP ^dvd$ CFUNCTION GLOBAL mksymlink sr0 dvd
REGISTER ^sr0$ CFUNCTION GLOBAL mksymlink $devname dvd
UNREGISTER ^sr0$ CFUNCTION GLOBAL unlink dvd

# Create /dev/cdrw for the first cdrom on the scsi bus
# (change 'sr0' to suite your setup)
LOOKUP ^cdrw$ CFUNCTION GLOBAL mksymlink sr1 cdrw
REGISTER ^sr1$ CFUNCTION GLOBAL mksymlink $devname cdrw
UNREGISTER ^sr1$ CFUNCTION GLOBAL unlink cdrw
- - %< - - - - - - - - - - %< - - - - - - - - - - %< - - - - - - - - - - %< - - - - - - - - - - %< - -

i guess this is self-explanatory.

i had this prob, you probably didnt incldue "generic scsi support" from the scsi section of the kernel config

give that a try. for me that made the correct /dev entries.
