- I have an Adaptec 1542B with a Fujitsu M2266S 1.08 GB disk drive. I do
- get over 1 GB of space with OS/2, though DOS only sees the first 1 GB.

- If you're talking about the upgrade that allows DOS to use disks larger

- multiple operating systems.

- No trick - it does work. Be sure you use the OS/2 FDISK and not the DOS
- FDISK to set things up.
