If you are needing a larger boot disk (you don't specify, and I do not see any reason that you would care, unless it is due to external space limitations), you may be out of luck. If you just need more disk space and do not care if it fits into the 310 case (no other disks will), look into buying expansion modules. Three routes: 1) adding a second disk to your 310 through the disk control and data ports on the back of the 310. An XM is sold for this purpose. 2) adding number 1) above and/or adding an XDC (eXternal Disk Controller) and associated expansion module (XM) to the 310. The XDC will support two disk drives, so that you could have three added by putting one on according to 1) and two more with the XDC. The XDC occupies one I/O slot. 1 and 2 both use the same disk drives that are put into the case, the options of which ar the 32 or 72 MB size. 3) Add SCSI to your system. (Small Computer Systems Interface) Numbers one and two may be cheaper (I do not know), but the SCSI interface will allow more expansion: up to 28 135 MB disks off of one I/O slot. (Yes, 28 X 135 MB = 3.78 GB!!) I am unsure at the moment of the exact size of these SCSI drives that are being marketed at the moment, but they are in the area of 135 MB. The SCSI interface will allow the connection of other devices other than disk drives. You can, for instance, configure it with a maximum of 24 disks and one 9-track tape drive (of course, you can put just one disk on it and expand it later...). -------------------------------------------------------------------------------- Randy Davis UUCP: ...(ihnp4!)3b2fst!randy 3B2 System Test Engineering AT&T Oklahoma City Works All opinions and/or advice stated above are MY OWN, not those of AT&T. --------------------------------------------------------------------------------
