The DOS 528 MB limit
If the same values for c,h,s are used for the BIOS Int 13 call and for the 
IDE disk I/O, then both limitations combine, and one can use at most 1024 
cylinders, 16 heads, 63 sectors/track, for a maximum total capacity of 
528482304 bytes (528MB), the infamous 504 MiB limit. This was already a 
problem many years ago, and all kinds of software, firmware and hardware 
solutions were invented. On the software side, there are Disk Managers, that 
circumvent the BIOS and go directly to the hardware. On the firmware side 
there are translating BIOSes, that use one geometry when talking to the 
disk, and another one when talking to the user program. (At best, this again 
allows access to 8.4 GB.) On the hardware side, there is LBA disk access, 
that no longer uses (c,h,s).

Tady píšou až 2G, ale záleží na BIOSu

jinak ještě:

upgrade to dos 7.10 and use fat32 (2Tb limit). You need to fdisk and format 
with a win95 OSR2/ win98 boot disk though, DOS 7.10 doesn't have these 
utils. on the boot disk.
