How can I mount in FreeDOS, if mounting other drives is even possible? If it is which types of media can be mounted and which ones can't.

What file systems are supported?
FAT32 is fully supported and is the preferred format for the boot drive.
Depending on the BIOS used, up to four LBA (Logical block addressing) hard disks up to 128 GB, or 2 TB, in size are supported.[38] There has been little testing with large disks, and some BIOSes support LBA but produce errors on disks larger than 32 GB; a driver such as OnTrack or EZ-Drive resolves this problem.
FreeDOS can also be used with a driver named LFNDOS to enable support for Windows 95-style long file names, but most old programs before Win95 do not support LFNs even with driver loaded unless they have been recompiled.
There is no planned support for NTFS, ext2 or exFAT, but there are several external third-party drivers available for that purpose. To access ext2fs, LTOOLS (counterpart to Mtools) can sometimes be used to copy data to and from ext2fs drives.

CDs and USBs is what I'm really interested in
Freedos supports CR ROM drives using xcdrom.sys
XCDROM.SYS
is an UDMA and non-UDMA CD-ROM driver for DOS.XCDROM.SYS
has to be loaded inCONFIG.SYS
/FDCONFIG.SYS
. When FreeDOS is already running, you can loadXCDROM.SYS
later withDEVLOAD
Source Command: xcdrom.sys
There are DOS USB drivers available, for example at DOS USB Drivers.
I've no idea whether they work with FreeDOS.

1Beware that this answer deals only with hard drives: CDs or USB drives require extra drivers, and those are not 100% guaranteed to work.– jarnoszCommented Nov 6, 2017 at 17:41

1CDs and USBs is what I'm really interested in (I don't need HDDs now). Can somebody tell me how to get drivers for them (CDs and USBs)?– HanlonCommented Nov 7, 2017 at 18:53

I have FreeDOS running on metal on a DELL Latitude X1 (Centrino-powered sub laptop). If you plug in a thumb drive before you turn on the machine, it will be counted amongst the drives available and get a drive letter in FreeDOS (If it has a VFAT filesystem on it) It also shows up as a 2nd drive in fidsk.
