mounting cdrom drives

[RYAN vAN GINNEKEN]

I have this in my dmesg output

acd0: CDROM <NEC CD-ROM DRIVE:28B> at ata1-master PIO4
acd1: CDROM <ATAPI CDROM> at ata1-slave PIO4

but when i try to mount these acd0 i get this error

#mount_cd9660 /dev/acd0 /cdrom/cdrom0
mount_cd9660: /dev/acd0: No such file or directory

so cd to /dev make device acd0 with this command
sh MAKEDEV acd0 seems to work no errors but the device is not created
and when i try to mount agian i get this agian

#mount_cd9660 /dev/acd0 /cdrom/cdrom0
mount_cd9660: /dev/acd0: No such file or directory

Please help
