Hello all,

	I have an original ibm pc at (model 5170, bios date of 11/15/85) running dos 4.01. I've added a 1.44 disk drive to the computer and can not get the drive to work correctly. Sometimes it reads and writes to the drive correctly other times I get a dos error 27 (can't find sector). 

	The internal disk drive checked out fine according to the technician at the dealer. He said that the bios was too old to support a 1.44 drive. The only solution would be to find a device driver to get around the old bios or install a 720 drive which should work.

	Has anyone successfully installed a 1.44 in an at this old? Does anyone know of a device driver that could be used to get around this problem? Would a  bios upgrade solve this problem, if so does ibm still sell these chips?

	Any and all assistance would be greatly appreciated.

	Please post or e-mail any info to dordaz@magnus.ircc.ohio-state.edu

							Thanks!
