Re: Saving system image to disk (NOT on a laptop)

Yeah...I was thinking of RIO which isn't 100% what Andrzej wanted...but maybe a step in the right direction? -marc Marc Nicholas netSTOR Technologies, Inc. http://www.netstor.com "Fast, Expandable and Affordable Internet Caching Products" 1.877.464.4776 416.979.9000 fax: 416.979.8223 cell: 416.346.9255 On Tue, 17 Aug 1999, Kris Kennaway wrote: On Tue, 17 Aug 1999, Marc Nicholas wrote: Wasn't there already a project that did this???

Re: Saving system image to disk (NOT on a laptop)
Hi, To all you low-level kernel and bootloader hackers: what would it take to save and restore a running system image (presumably from dedicated raw partition) so that the system would continue where it left before reboot? It doesn't sound that difficult to me - after all, laptops somehow do it - but I know too little low-level stuff to try implementing it myself... It's quite difficult, in that it requires intimate low-level knowledge of the hardware in order to save/restore its state correctly. In the case of laptops it's much easier because the hardware can't be changed under the image, and the BIOS knows all about the hardware. To do it right in the generic case, you'd virtually have to go through the entire boot process again. It might make more sense to try an alternative arrangement whereby you paged _everything_ out to swap, then saved the entire kernel data and bss segments somewhere. You'd have fun at the restore's cutover point though, and any stateful hardware would still be a bitch to deal with. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msm...@freebsd.org \\-- Joseph Merrick \\ msm...@cdrom.com To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-hackers in the body of the message
