What kind of hardware environment - i.e. disk capacity?, ATA-100/133?, mobo type? CPU clock? In addition to what I mentioned, I'm using an MSI 6561 SiS 745 mobo w/ Athlon XP 1800 w/ DDR RAM. ---------------------------------------------------------------- John Karns [EMAIL PROTECTED] ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _____________________________________________________________________ Ltsp-discuss mailing list.
