I just compiled and installed that dosbox on Linux, it seems to emulate[snip]
a complete DOS PC, and it even sort of runs vrs.exe (3D flight
HOWEVER it tries strange things with my harddisk: dmesg:
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x54 { AbortedCommand
LastFailedSense=0x05 } ide: failed opcode was: unknown
ATAPI device hdc:
Error: Illegal request -- (Sense key=0x05) Cannot read medium -
incompatible format -- (asc=0x30, ascq=0x02) The failed "Read
Subchannel" packet command was: "42 02 40 01 00 00 00 00 10 00 00 00
00 00 00 00 "
Now hdc is the CDROM in my case, so it cannot do any harm I suppose, but
check with dmesg if it does not corrupt anything on your system.
This probably is unrelated [1] and/or dosbox might not have an
option setting for it, but see section 11.2.2 on page 113 in
http://www.virtualbox.org/download/1.6.2/UserManual.pdf
that mentions a bug in the hard disk driver of Windows 2000 -- "a race
condition in the Windows driver code which leads to corruption if the
operation completes too fast" [as may occur in a virtual environment].
For virtualbox, there's an option to increase IRQDelay during installation.

[1] Ie, your error messages appear in the linux log, vs errors from
the Windows bug show up in the virtual machine.
