Re:FDC doesn't work on real PC

The sad thing is floppys are slow, but have you made a fat12 driver yet, if not you will need to make one, for code to do this you can take a look at Dex4u source code it got drivers for fdd, hdd, atapi. fat12, fat16, fat32,You will find the source on this page:
http://www.dex4u.com/download.htm

Note reading from HDD is a lot easier that FDD so once you happy with your fdd code you will find HDD easier.
If you down load Dex4U you can see the speed compeared too yours.
@Candy, There is still little differance on a p2 233.

There was this point on "d*mn slow" that was intended to show that you'd need a 386 or so to show a noticeable effect. Do the maths (as I've tried to get you to do a few times before, on other occasions):

@Candy,There are also people who talk about making things and people who make things, please can you post a link to you floppy driver, so i can test it against mine for speed.

Oh you have made a floppy drive, if not, Do the coding (as I've tried to get you to do a few times before, on other occasions):

You need to remember coding is a art just as much as a science.

@Dex4U: Now, first, step back from having a go at others & taking their own words to build a retort (as if that were necessary). This is not the place for living out peronal animosities.

Second, you are perfectly wrong: First you do the maths to find out an appropriate algorithm. building fine algorithms IS maths. This has zilch to do with being a good coder. anyone can be a good coder given enough training, but not everybody has the brains to do a proper analysis ere starting to design and code.

What Candy talks about among other things (if you have even cared about) is optimizing the head movements as in "Where to put the head next": your average hdd is able to apply head movement optimizing on the fly as fits, but not your average floppy. So you have the choice between several algorithms: Shortest Distance first ( takes differences between the nodes to read and sorts them according to the necessary head movements, so the longest movements come at last ), sweep algorithm (read all the tracks, first move head to the right in lenght of the disk radius, then move head left across the disk diameter), and some more (don't remember them at the moment, have to look up). Further this is about optimizing the reading operation by fetching tracks in the most optimal way to avoid too much of disk spinning ere the reading can start.

If you 'd care to read & think ere posting sullen retorts, Dex4U, you 'd be more favourable a member here, but given this your manners of being stubborn & disgruntled coz of the smallest of incidents makes me thinking twice ere replying or asking you something.

Coding is handcraft. build the algorithms is the art. And thats science.

STay safe.

All i am trying to do is help some people with there OS coding, i do not need addvice from heavy hand modders, who have not even code a floppy driver.
Take just the last two posts this one and this one
http://www.mega-tokyo.com/forum/index.p ... eadid=9491

What is the problem, just lay off or there will only be two regular people left on the forum, who can code, Brandan, Pype.Clicker.
Have a nice day .

I'm sorry for dex4u to say this, but I completely agree with beyond infinity. Making a good design and fast and working algorithms is an art, coding itself is not]/b]. Even a monkey can be learnt to program, but only few can design good algorithms. I'm not saying you don't need to learn coding, only that making good algorithms is much more difficult and important.

The only thing I can see in the post you mention is you giving asm code which was not asked for and not helpfull either. I remember you doing that a lot lately, posting lots of asm which nobody wants. I respect your choice to code in asm, but I don't think may people here want to read a lot of asm to code a floppy driver. I think most prefer C.

Not much as changed .

@dex4U: man, quit being such a prat! This is annoying.

What think you have I done? I have analysed, designed and developed an operating system, which has among other things a quite stable floppy driver. Unlike YOU, I do not run around like a but-so-cool-jack-a-all-trades and force my stuff down everyones throat's.

Have a nice day.
