i have installed neutrino 6.2.1 non commercial and it seems nothing is
working or i don’t know how to make it work. for example i can’t reach my
cdrom or floppy. if i type fsys & QNX says that file not found if i use
/dev/cd0 then QNX says that i do not have rights. if i type fsys.floppy & it
do something but on the end it says that file not found. every command
within filesystem returns me an error.
This is from the 6.3 Neutrino User’s Guide, but it should help you:
The driver for a floppy drive is devb-fdc. In order to use a floppy
disk, you need to ensure that the floppy controller is enabled in the
BIOS, and that the BIOS is configured to recognize the correct type of
floppy drive (e.g. 1.44MB/2.88MB). The driver uses these locations as
- I/O port 0x3f0
- IRQ 6
- DMA 2
If your controller is located at a different address, you can change
these locations in the driver’s options.
The default cache size specified by io-blk.so is 15% of system memory,
which is excessive for devb-fdc. You’ll probably want to reduce it to
something more reasonable:
devb-fdc blk cache=128K &
The driver creates a /dev/fdx entry, where x is the number of the floppy
drive, starting at 0. If no entry appears, the BIOS settings might be
incorrect, or there could be a problem with the controller. Check the
output from sloginfo for clues.
Once you have an entry in the /dev directory, you need to mount the
floppy disk. The mount command detects the type of filesystem you’re
using (e.g. DOS, QNX 4), but you can also specify it on the command
- To mount a DOS-formatted floppy disk, type:
mount -tdos /dev/fd0 /fs/dos_floppy
Use mkdosfs to format DOS floppy disks and DOS hard drives. This utility
supports FAT 12/16/32.
- To mount a QNX 4-formatted floppy disk, type:
mount -tqnx4 /dev/fd0 /fs/qnx_floppy
You don’t need to remount the drive when you change floppy disks.
Don’t remove a floppy while the driver is still reading or writing data;
floppies are quite a bit slower than hard disks, so it can take a while.
Make sure the drive light is off.
