So I recently got a packard bell legend 1155 using the 430 motherboard

Here's some reference info to peruse http://www.uktsupport.co.uk/pb/mb/430.htm

I should say this is my first windows 3.1 system I've ever used but not my first 486.

The issue I have is the floppy drive will hang. I insert a working floppy (working via a windows 98 packard bell machine at least) , I select the A drive in the file manager , the light on the drive lights up showing that it's trying to read the disk , then nothing. The machine is then stuck in limbo , I assume waiting for the A drive to respond. The mouse still moves but I can't click on anything and it never shows the contents of the drive.

I also tried dos. Trying to change the C prompt to A , results in the drive trying to read but giving up leaving me in limbo in dos with a blinking cursor. Ctrl alt delete still works and restarts the machine.

Things I tried

Tried two different 3.5 disk drives both react the exact same way.
also check the bios to make sure the A drive was set correctly and it was. I imagine if it was set wrong it wouldn't try to read the disks like it is anyway.
Made sure cable wasn't flipped. (flipping it yeild a solid seek light on the drive anyway so I know it's in the right way).
Tried one disk made in a windows 98 machine , then tried a bone stock windows 3.1 driver disk for a plus hardcard just to see if it would read that and nope it didn't read it.

Hmm. Do the lights on the floppy drive light up and did you run CheckIt! on that system ?
Maybe the DMA controller is having trouble. The Floppy Disk Controller uses DMA2/IRQ6.
Also make sure things like EMM386 or UMBPCI are not running while you are testing.

(It is unlikely, but sometimes a too slow/fast ISA bus can cause trouble with floppy drives.
Same with certain IDE drives or Compact Flash cards.)

The lights light up , i can't run anything on the machine as the floppy isn't working and it's the only way to get information into the machine.

so how would i go about check for those?

well if it at all help the machine is using the original drives all the way around. So at least i know that it technically COULD work

If you boot bypassing startup files by pressing F8 will make sure emm386, or anything have loaded.
Not to sure how to check DMA, I have Norton Utilities but I's sure something free is available for dos

I would also try another cable, I would have blamed the drive but you have eliminated that as a possibility

I must admit that I'm not really familiar with Packard Bell systems, thus I will ask...is the floppy controller built into the motherboard, or is it on a separate card? If it is on a separate card, have you tried moving the card to a different slot? Oxidization on one or more of the pins could conceivably cause issues, although to what degree I could not say due to having never encountered this specific problem myself.

In a similar vein to what I said above...have you tried a different cable? It's possible the cable that came with that old computer could have some breaks or oxidization preventing some of the data lines from working, thus causing the soft lock when trying to access the drive. It might also be worth trying to clean the floppy connector on the motherboard/controller card with some deoxit or similar.

You also said that you had checked the BIOS settings...have you tried resetting the BIOS outright, either by selecting the Load Defaults option or by pulling the backup battery for a few minutes? I doubt this is the cause, but it's still something worth trying.

You said the access light will come on when trying to read a disk...but do you hear the disk spinning? Again, having never encountered this exact problem I cannot say for sure if this is the cause, but just a theory on my part could be the power connector being faulty, or again possibly have a broken cable. I'll confess a lack of technical knowledge to the intimate workings of a floppy drive, but my thinking is that if the drive is receiving 5V but not 12V, the circuitry and whatnot of the drive might work, but it will be unable to spin. Perhaps, if possible, try a different power connector.

Just some random ideas of things to check to hopefully help either solve the problem or at least eliminate potential causes.

Hi, CheckIt! checks the DMA channels if you select the mainboard test.

IRQ6, on the other hand, can be checked by Microsoft Diagnostics (MSD).
(CheckIt! also can show IRQs, but usually does not list any floppy controllers)

Edit: You can also give Dr. Hardware a try. 😀
Maybe it can do similar tests (I am not sure, since it has been a while since I used it).

Are both of those located on the hard drive? Because the floppy doesn't work.

Alright i tried a new floppy drive and new cable , made sure it recognized that it was plugged in and being identified correctly. (essentially fool proof as there is only one way it can be connected without displaying an error or locking u the machine)

Still doesn't work , just tries to seek the drive then softlocks the machine.
