Problem:

Step:

1. Create 2000 mb image with bximage from bochs:

C:\Program Files\Bochs-2.6.11>bximage

Creating hard disk image 'c.img' with CHS=4063/16/63 (sector size = 512)

1. Use DBGL 0.91 with Dosbox 0-74.3 to create the following config profile:

[cpu]
core=dynamic
cycles=83500
cycleup=4000
cycledown=2000

[sdl]
output=opengl
fullresolution=1280x960
windowresolution=1280x960
fulldouble=true

[render]
scaler=none forced
aspect=true

[speaker]
tandy=off
disney=false

[joystick]
joysticktype=none
timed=false

[dosbox]
captures=..\captures\2

[autoexec]
imgmount A "E:\emu\dos_newme\!win95\boot95.img" -t floppy
imgmount 2 "E:\emu\dos_newme\!win95\c.img" -fs none -size 512,63,16,4063 -t hdd
boot "E:\emu\dos_newme\!win95\boot95.img"
a:
dir
exit

1. Boot Dosbox using win95 bootdisk or dos 6.22 bootdisk
2. Run fdisk
3. Create the primary partition with the full extent
4. Check its size before exiting fdisk

Expected:
FAT16 primary partition of size up to 2Gb can be created.

Actual:
FDISK reports 488 mb available.

Additional environment info:
Win 10 x64
DBGL folder has "compress" flags enabled, so image, dosbox, dbgl are all compressed on disk using NTFS compression feature in Win 10.

1023 is maximum cylinder count, so you need to increase head count.
