Guess I should admit from the start...
You should only need the XP install disc, it comes with pretty much all the tools one would need to recover a broken system if there is any hope of recovery. The only scenario I can think of where you would absolutely need floppies is when you simply can't use the installation CD because you don't have one or because your CD drive is broken/unable to be used as a boot medium/non-existent or such.
Such expansion cards do exist but I don't come across them very often.
What exactly are you trying to achieve?
I'm a newbie and understand little of this. That said, I asked question long ago on various forums as to whether or not I have to include internal floppy drive in my custom build. The consensus was that its required for XP Pro. Now I got no real idea what "emergency situations" someone meant, as no details were given, but tentative Google search turned up a lot, including :
1. A bootable floppy disk is required to create a restore disk for antivirus or backup software.
2. On older OS's like XP Pro, you "still need to use internal floppy for drivers that need to be loaded at beginning of an install."
3. Some motherboards will "only read the BIOS flash from an internal floppy drive."
4. If BIOS has boot block it will "run a floppy drive from which you can run a flashing program. If your BIOS is corrupt but it has boot block, it will boot your PC to floppy."
There were lots of other hits, but I've no idea what is or is not relevant, so won't waste forum space quoting possible minutiae.
Anyway, right now I'm just trying to get definitive answer for:
1. To keep XP Pro (and maybe Windows 2000 & Windows 98) up and running, do I absoultely have to include floppy drive in this build?
2. If yes, does it absolutely have to be
internal floppy drive (i.e. no external floppy drive, CD, DVD, flash drive, etc., will suffice)?
3. If yes, is there way to add
internal floppy drive to motherboard not having it?
I'm now looking at motherboards, and which ones I can eliminate and which ones I can consider depends on these answers.If I don't have to have floppy drive at all, or can use external one, then problem solved. If I absolutely must have internal floppy drive, that limits choices to only a few....unless there is way to install internal floppy drive on motherboards lacking it.
As for eSATA and FireWire, I do require these. Now if they can be install on motherboard lacking them, I got loads to choose from...if not, that eliminates all the motherboards not having one of both.
