I have an old 486 or early Pentium computer with a dead Hard drive and it seems that the boot floppy (a 5 1/4 drive) is dead also. It has a 3.5 inch floppy also but it will not boot from that drive. How can I change it so it boots from the 3.5 inch floppy?

If the BIOS is new enough, put the 3.5" at the end past the twist and with luck it'll boot. If at first you don't succeed, you're about average. M2

You may need to replace the floppy cable with a *modern* one - those old drives used an edge connecter. Some cables would have both the pin and the edge style connecters - but (as stated) it's the drive plugged in after the 'twist' that is seen as the boot drive "A:" On a 486 (and indeed nearly anything) the BIOS won't be an issue, but you will likely have to change the configuration there to reflect the new setup Resist the temptation to close your request for help with semantically-null questions like “Can anyone help me?”

That did it I just connected up the 3.5 inch drive after the twist in the cable and unplugged the 5.25 inch drive. You were right the 5.25 inch drive had an edge connector. I had to correct some CMOS and BIOS settings but it is up and running thanks for all of your help. It is actually running Win 95 on a 486 55 Mhz processor.. I did not think that Win 95 would run on a 66 Mhz 486... Thanks again

Sure it will, and reasonably well if you have enough RAM (16Mb+). The minimum specs claim a 386DX with 4Mb are enough (but hardly recommended) Glad it all worked out for you Resist the temptation to close your request for help with semantically-null questions like “Can anyone help me?”
