Have a look at my freeware IFS-based RAM disk for OS/2. Source code
included.
Features
- Create as many RAM drives as you want, using the drive letters that
you want
- Size only limited by available RAM and swap disk space
- Allocates swappable RAM from OS/2 as necessary when files are created,
and releases it again when files are deleted
- Long file name support like in HPFS. Case isn't significant, but
preserved like in HPFS. Files with long names are not visible from DOS
and WINOS2 programs.
- Extended Attributes - up to 64 KB total for each file/directory (HPFS
supports up to 64 KB for each EA, up to 256 KB total for each
file/directory)
- RAM is allocated in units of one page (4 KB)
Installation and use
Add IFS=d:\path\RAMFS.IFS to config.sys and reboot. Then, from an OS/2
prompt, use RAMDISK.EXE to create a RAM drive. To create a drive R:,
type RAMDISK R:
To have a RAM drive created at every boot, you can add
RUN=d:\path\RAMDISK R: to config.sys.
