Could you possibly paste your /etc/fstab? Maybe some error messages?

romalong,
First, you need to mount your CD or floppy. Only root can do that unless you have the option user in /etc/fstab.
You also need the iso9660 filesystems and its extensions available to the kerne for CDROM (UDF is useful if its actually a DVD and/or a writer.
For floppy, you need VFAT and friends, for normal DOS format floppies. If you are not in the USA be careful that your actually build under NLS, the code page you have selected as the default for VFAT.

romalong,
I don't know what codepage you would choose in Kiev.
The point is that whatever you have selected to use as defualts for VFAT under the options
| Code: | Default codepage for FAT
Default iocharset for FAT |
must also be selected to be compiled under
| Code: | | Native Language Support |
or mount will fail with a non relevant error message.
The defaults are for American English (if there is such a thing)

romalong,
Here you are:-
Navigate to
| Code: | Device Drivers
File systems
CD-ROM/DVD Filesystems
|
and choose
| Code: | ISO 9660 CDROM file system support
Microsoft Joliet CDROM extensions
UDF file system support
DOS/FAT/NT Filesystems
MSDOS fs support
VFAT (Windows-95) fs support
Default codepage for FAT (I Use 437)
Default iocharset for FAT ( I use iso8859-1)
Base native language support
Codepage 437 (United States, Canada)
NLS ISO 8859-1 (Latin 1; Western European Languages) |
The Defaults selected under VFAT, are what the VFAT filesystem will try to use.
The Selections under Base native language support determine whats actually available.
If the defualt is not available, mount will fail unless you pass it an option to tell it what to use.
In your fstab you don't have a line for your floppy either. Its not essential. I have
| Code: | | /dev/fd0 /mnt/floppy vfat noauto,rw,users 0 0 |

i've followed your tips, but:
| Code: |
base ~ # mount /dev/fd0 /mnt/floppy
mount: /dev/fd0 is not a valid block device

romalong,
Well, that shows how often I use floppies these days.
Watch this space.

romalong,
Sorry. Its slang. It fails for me with the error | Code: | | mount: special device /dev/fd0 does not exist |
It means I will investigate further and post again.
========== edit ===============
My udev rules should create a /dev/fd0 but don't - this is not going to be quick

romalong,
It works. I had forgotten that I had configured my floppy module as a module and not set it up to auto load.
In make menuconfig its at | Code: | Device Drivers
-> Block devices
-> Normal floppy disk supporr |
With it built as a module (like sound), you can then mount will work.
You also need to add yourself to the floppy group or you will get permission denied errors.
Log out and back in for it to take effect

should it be
| Code: |
<M> Normal floppy disk support
|
where can i find
can you explain me what's the difference between <*> and <M> please? |

romalong,
The kernel comes in parts, when you do you are specifying which parts you want to use and how they should be assembled.
| Code: | [*] means put this part in the kernel file that is copied to /boot
[M] means put this part in /lib/modules/'uname -r'/...
[ ] means leave this out altogether |
When you change a setting to [*], you need to rebuild your entire kernel, install it, then reboot for the setting to take effect.
When you change a setting from [ ] to [M], then | Code: | make modules
male modules_install |
compiles the new module and puts it in the proper place in /lib/modules/'uname -r'/... so that modproble can find it. No reboot required.
You can also add the module name to /etc/modules.autoload.d/kernel-2.6 so that the module is automatically loaded.
You should be able to answer your own question now. I use a module [M] because I rarely use the floppy.
I also use modules for new things I'm trying - it saves reboots.
You can use [M] now and change it to [*] when you upgrade the kernel. You have to change the content of /boot then anyway.

when i enable modules, i need to do:

# male modules_install |
and when i use <*>, i have to use:
am i right? |

romalong,
If you have changed even one selection from [ ] or [M] to [*] you must rebuild and reinstall the entire kernel.
There is one small exception which is not easy to spot in make menuconfig (it stands out well in make xconfig)
in the case of a few items, they have sub items which can only be [*] or [ ]. However, they follow the parent item.
An example will help. Look at | Code: | | Bt87x Audio Capture |
in Sound -> Advanced Linux Sound Architecture
-> PCI devices.
When Bt87x Audio Capture is selected as either {M] or [*] the item Bt87x Audio overclocking is shown. Bt87x Audio overclocking can only be [*] or [ ] but it is an optional part of the Bt87x Audio Capture module and its the selection against Bt87x Audio Capture that determines if the optional part is [M] or [*]
In make xconfig (which requires X), these things are indented to make it clearer.

i've removed noauto option from fstab on cdrom and floppy.
so now cdrom works well, but floppy doesn't.
also there's error during bootup, it says that some partitions are not mounted.
obviously, it's my floppy. |

romalong,
The floppy should be noauto because it may not have a disk in at boot time.
If you made the floppy kernel module as module, you need to do to load it or add floppy to /etc/modules.autoload.d/kernel-2.6
