Actually, I remember installing FreeBSD 4.0 on my Dell Inspiron 7500, both suspend to disk, and suspend to memory worked *perfectly* Unfortunatly it hasn't worked on any recent versions of FreeBSD, not sure when it broke. Inspiron 7600's do S4 via the BIOS and write the memory contents to a fat32 partition, there is a small utility to set the 'save-to-disk' file. It was also fine in 4.1 IIRC, some day i'll find the time to figure out why it dosn't work anymore. Amar. -- http://www.ten15.orgReceived on Tue Jan 13 2004 - 22:06:27 UTC
