Hi, can anybody remember to have used a SCSI CD-ROM with Hurd ?
I tried to get access to a virtual one created with kvm: -drive file=/dvdbuffer/netinst.iso,if=scsi,bus=4,unit=0,media=cdrom but after booting Hurd, there is no /dev/sr0. gnumach/linux/src/include/linux/major.h has #define SCSI_CDROM_MAJOR 11 So i did mknod /dev/sr0 b 11 0 and rebooted. Something is still missing, though: $ su Password: # dd if=/dev/sr0 bs=2048 skip=16 count=1 | strings dd: opening `/dev/sr0': Permission denied # ls -l /dev/sr0 brw-rw-rw- 1 root root 11, 0 Sep 15 08:16 /dev/sr0 # I get the same error message if i try to read from /dev/sr0 when no SCSI CD-ROM is emulated. An emulated IDE/ATAPI CD-ROM behaves quite as expected # dd if=/dev/hd2 bs=2048 skip=16 count=1 | strings | grep CD001 1+0 records in 1+0 records out 2048 bytes (2.0 kB) copied, 0 s, Infinity B/s CD001 # kvm's SCSI CD-ROM emulation works with a RIP Linux rescue image. RIP does not come up with -boot d from the emulated SCSI CD-ROM, but if i submit RIPLinux-9.3-non-X.iso by -cdrom and the Hurd netinst.iso by above -drive option, then i get a /dev/sr0 from which i can read the PVD of Debian GNU/Hurd netinst.iso. (RIP's own ISO image appears as /dev/hdc.) Have a nice day :) Thomas
