Therefore I provide this practical sample which worked for me (I am not replacing README here - see there for details about commands IMGMOUNT and BOOT). The following was tested using bootdiscs for MS DOS 5, MS DOS 6: 1. I created a 10 MB disc image using bximage.exe utility from Bochs http://bochs.sourceforge.net (below are details): Do you want to create a floppy disk image or a hard disk image? Please type hd or fd. [hd] hd Enter the hard disk size in megabytes, between 1 and 32255 [10] I will create a hard disk image with cyl=20 heads=16 sectors per track=63 total sectors=20160 total size=9.84 megabytes What should I name the image? [c.img] Writing: [] Done. I wrote 10321920 bytes to (null). The following line should appear in your bochsrc: ata0-master: type=disk, path="c.img", cylinders=20, heads=16, spt=63 2. I put the HD image (c.img) together with an image of a bootable floppy (msd60.ima) into the directory d:\dosbox on my disc. 3. Then I went on with creating of a patition on the disc. I started DOSBOX with the following lines: mount d: d:\dosbox imgmount 2 d:\c.img -size 512,63,16,20 -fs none boot d:\msd60.ima 4. After DOS booted I started FDISK and created a primary DOS partition. When FDISK wanted to reboot later, it crashed/froze (depending on DOS version). I ignored it and ended DOSBOX (it is minor nuisance but FDISK already did its work). 5. I again restarted DOSBOX as in the point 3., but instead of FDISK I used: FORMAT C: /S This formatted the disc and made it bootable. 6. Now the disc was usable - either for booting or when mounted from DOS shell. For booting I did this: mount d: d:\dosbox imgmount c d:\c.img -size 512,63,16,20 -fs fat boot -l c WARNING: Do not copy files to harddisc image from DOSBOX shell when using DOSBOX 0.63 or lower version. It corrupts the image !!! This was fixed in CVS - so use CVS build if you want to do it. DISK EXPLORER If you need to get some files to/from the disc images, you can use the DiskExplorer available on http://hp.vector.co.jp/authors/VA013937...dex_e.html (choose VMWare format). IMGMOUNT defaults If somebody is wondering why I did not specify parameter -t for IMGMOUNT: I did not have to, its default value is "hdd". The parameter -fs has also a default value ("fat") - so "-fs fat" was also not needed. Mirek
