This new thread is about the newbie user problem to set up
what i want to test on the long term.
I am thankful for any proposal.
> # settrans -cfgap /dev/sr0 /hurd/storeio sr0
I removed my mknod-made /dev/sr0 and executed above command.
No protest message.
# ls -l /dev/sr0
brw-r--r-- 1 root root 0, 0 Sep 15 14:17 /dev/sr0
But:
# dd if=/dev/sr0 count=1 bs=2048 skip=16 | strings
dd: opening `/dev/sr0': No such device or address
#

no

I read in gnumach/linux/src/drivers/scsi/sr.c:
if (register_blkdev(MAJOR_NR,"sr",&sr_fo ps)) {
For comparison:
In gnumach/linux/src/drivers/scsi/sd.c:
if (register_blkdev(MAJOR_NR,"sd",&sd_ fops)) {
In gnumach/linux/dev/drivers/block/floppy.c:
if (register_blkdev(MAJOR_NR,"fd",&floppy_fops))
But i see in /var/log/dmesg
hd0: got CHS=1024/255/63 CTL=c8 from BIOS
hd0: QEMU HARDDISK, 32768MB w/256kB Cache, CHS=4177/255/63, DMA
hd2: QEMU DVD-ROM, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
FDC 0 is a S82078B
Failed initialization of WD-7000 SCSI card!
No SCSI card, so no SCSI CD-ROM ?
man kvm on the hosting Debian amd64 does not tell much about SCSI
other than examples how to set up emulated SCSI drives.
The message about CD-ROM at hd2 comes even if i submit no -cdrom to kvm.
Trying to read it then yields
# dd if=/dev/hd2 count=1 bs=2048 skip=16 | strings
dd: reading `/dev/hd2': Input/output error
> Also, there is a /dev/MAKEDEV script.
This seems to have no case that matches device name "sr".
Have a nice day :)
