[SunHELP] HOWTO compress and save large SunPCI-dmg ... Update!

[Michael Karl]

Compress works well, but the compression is only 13GB of the 21GB-Diskimage.
Gzip (1.3.5) works better ... 9GB of the same 21GB-Diskimage ... but needs
more then 5 hours (Compress 2,5 h).

"cat winxp.diskimage | /usr/local/bin/gzip > winxp.gz"

Any other hints anyware ?
