I'm trying to load OpenDOS 7.03 (only) onto an HP Pavilion 6336 K-6 machine w/ 8MB Quantum Bigfoot HD that came with Win98SE on it. (I ran all utilities from A:.) 1) Ran FreeFDisk and removed partitions to start fresh. 2) Using FreeFDisk, created bootable primary 2GB (2052MB) FAT16 partition. 3) Created extended FAT16 partition and logical drives D:(2GB) E:(2GB) and F: (1506MB) 4) Formated C: with OpenDOS 7.03 FORMAT c: /S/U/X. 5) DIR and OpenDOS install program show only 4,292,608 bytes on C: (OpenDOS will not install due to insufficient disk space.) (Also tried repartitioning the HD w/ the OpenDOS 7.03 FDISK and the NovellDOS 7 FDISK to no avail. Also tried using the OpenDOS and NovellDOS versions of FORMAT to no avail.) 6) D: drive will not format (get INVALID DRIVE error message) 7) Checked BIOS setup and tried OS settings for both "OTHER" and "WIN95" with no apparent effect. Nothing I have tried results in more than 4,292,608 bytes of disk space on C: What am I not doing right? (It's been awhile since I last did this, and the last time I loaded DOS it was to upgrade to a newer DOS on a HD that already had an OEM DOS installation.) Ken R,

Run fdisk, Y to large disk support and then option 4. Exactly what does it say?

OpenDOS was 7.01 or 7.02, 7.03 is DR-DOS. It only supports FAT16 2GB max partitions. http://www.killdisk.com will wipe the drive, then boot from DISK1 of DR-DOS 7.03: http://www.drdos.com/dosdoc/index.htm http://public.planetmirror.com/pub/...

When I run FDISK and answer "Y" to Large Disk (FAT 32) Suppport I get the following: Partition Status Type Volume Mbytes System 1 A PriDOS Main 2052 FAT16 2 ExtDOS 5611 Ext.LBA Total Disk Space 7671 Mbytes When I display the logical drives in the Extended Partition, I get: D: 2052 Mbytes FAT16 E: 2052 Mbytes FAT16 F: 1506 Mbytes FAT16L

The partition size shows 2 gig but there's only 4 meg available. Depending on what commands you have available on your bootdisk, try running chkdisk c: or attrib c:. That will show hidden file that the DIR command won't. Otherwise it's probably best to wipe it and start over as dosser suggests.
