|To do the DMF format download this:|
Extract FDformat.exe and FDRead.exe and place them in a folder named in your Path statement or the root of C:\. Load FDRead.exe which is a Terminate and Stay Resident (TSR) program that allows for extended access beyond the normal sector/track count. Then run Fdformat with the following parameters:
fdformat a: c4 d16 f168
Which will get you 21 sectors per track instead of the normal 18 with a one sector directory and a cluster size of 2048 bytes instead of 512. For exactly 1,716,224 free bytes which will fit one 95b or 98 Gold cab file. Name the volume of the disk according to the disk number as found in layout.inf file and Setup will call out for it when needed. Or just move the cab files over to the target machine's hard drive and install Windows from the hard drive for the best results.
The first disk in a floppy install set MUST be done at 1.44 meg size because it is the running of setup.exe on that disk that allows the reading of the other 1.68 size floppies - they can not be read otherwise, normal DOS does not allow for it.
There are NO floppy images of 1.44 meg size that install Windows 95 or 98 so you will be looking for them for a long time.
In order to do 98se size try:
fdformat a: c64 d1 t:84 n:21 h:2
But don't expect to get a working floppy as most drives can't even read this very special format let alone write to it nor do the format properly. Windows will REPORT that you have 1,802,240 free bytes which fits the 98se cab files exactly but it's just faking that part - chances are very high that the disk is actually useless. The exact parameters are 84 tracks and 21 sectors/track, 32k cluster size, one root directory sector, with two fat sectors.
ONLY other floppy method is to split the cab files and move them over to the target machine using two standard floppies. Use the internal DOS command Copy to merge the two files back together and they will work perfectly - special formats not required.
I covered that subject in full here
Can we beat this dead horse any further?
