![]() Even if you only want a single drive letter, say C:, for the entire drive, you must still run FDISK and define a single partition. Not sure if this applies to bootable CD iso, though. Step 2) Run FDISK FDISK.exe is an external DOS command which is used to 'partition' the hard disk (split it up into usable areas) after it's been low-level formatted. I think this is hard limit regardless of which MS-Dos version youre using. For some reason, this won't work if the HDD is mounted as a slave.Ĭreate a primary MS-DOS partition, use all the available size. 2 Answers Sorted by: 0 This is because Microsoft limited the boot disk size to 1.44 MB for optimum compatibility with largest number of BIOSes available. Mount the bootable MS-DOS disk in Floppy A: and image.vhd in IDE 0-0. Enable the checkbox beside Create an MS-DOS. The number 516096 was chosen to match the size of a cylinder that has 16 heads and 63 sectors (16 * 63 * 512 bytes per sector), because to my understading XTIDE likes to address disk images by using the maximum allowed amount of heads and sectors per cylinder but you can use whatever number you like, the final image will be count * bs bytes large. Figure 3-2: Windows Format Startup Disk Screen Right-click A: drive. This will create a file named image.vhd which is about 2 * N MiB in size. $ dd if=/dev/zero of=image.vhd bs=516096 count=N If you have a minute you could post the step by step how to make it again, I will try to replicate.įor the record, I managed to create a working HDD image from within MiSTer with the following instructions. Even though in theory seems we are making them in the same way. ![]() And I would've though that the BIOSes in ao 486 and PCem I've used were already capable of handling that any chance you could zip and upload this (empty) 1GB Hdd of yours somehwere? I'd like to test it vs my files. Example: The line 'DRIVPARM/D:1 /F:9 /C' in the CONFIG.SYS file specifies that the floppy disk drive B is a 2.88-MB 3.5-inch floppy disk drive that supports the Change line. ![]() I also read that FAT16 is capable of making 2GB partitions. I would prefer if someone could show me where to get Microsoft MS-DOS 2.11 and how to install it on it that would be much appreciated. Ensure that the disk is inserted rightside-up. I want to put DOS on a floppy drive so I can install it on my Sharp 7000. Make sure that the disk is inserted before you go looking for it on your computer. This 530MB limit seems more related to some of the other ATA/HDD limits but I'm not sure why. Messages 4 Location Iowa, United States 1 I got my 5.25 high density floppy to be seen by Windows 7. Not sure if the amount of files can affect things in general, I was reading about space loss due to cluster sizes (so 100kb file becomes 128kb) in FAT 16 but still even with that considered not sure it could've accounted for my case (only 530 GB fitting into a 1GB+ hdd). But all this is kept in separate directories, not root. Overall the collection I need it for has a huge amount of files - approx 74K files in 4000+ directories. You can have Setup format this drive for you, or you can exit Setup and format. I don't have many files in the root, just a handful of normal DOS ones. MS-DOS 6.22 cannot use unformatted drives.
