Re: hibernation solution
Date: Thu, 5 Jul 2001 15:34:24 -0400 From: "Lawrence Young" <[EMAIL PROTECTED]> Subject: Re: hibernation solution Here is my simple solution: (1) attach the HDD to Lib and run FDISK to allocate the primary partition to the maximum it can handle. (2) attach the HDD to desktop machine with Win2K and create a dummy partition of size 150MB right after the first partition created by Lib. This is the space for hibernation data. I figure 150MB should be enough. (3) Create and format a third partition from Win2K right after the dummy partition. I ran Win2K on my L100 so there is no problem seen the extended partition.

This should take care of it. taken from: http://ta.twi.tudelft.nl/DV/Staff/Lemmens/libretto70ct.html Get the hibernation mode working on the larger harddisk The only thing that caused me a real headache was the hibernation mode that uses a part on the harddisk to store the memory while the Libretto was switched off. If this part lays somewhere in the middle of a Linux partition the latter will be partly or wholly destroyed after one hibernation In the original disk simply the last 18 cylinders were reserved for hibernation : raw size of 1.6 GB disk :788/64/63 (C/H/S), Linux usable size :770/64/63 (C/H/S) However, with this new disk things were much more complicated as the Libretto BIOS - just like many older PCs - can't recognize disks larger than 8.4 GB. After some disasters (a trashed second partition and a trashed swap space !) I found out that hibernation takes place in the first sectors AFTER the 8.4 GB. To put things absolutely clear: it is NOT at the end of the 10 GB and it is also NOT just BEFORE the end of the 8.4 GB. After finding this out I decided upon the following partitioning scheme that already works flawlessly for some time without causing any damage to the Linux partitions after several hibernations and fscks / memory checks : Layout of the 10 GB disk : 1222 cylinders, 255 heads, 63 sectors My partitioning scheme : Linux partition :1 - 192 (1.5 GB) Work partition : 193 - 1015 (6.5 GB) Swap partition : 1016 - 1023 ( 64 MB) Hibernation : 1024 - 1929 ( 48 MB) (can be smaller : only need 32 MB) Third partition : 1030 - 1222 (1.5 GB) Fdisk reports the following : Disk /dev/hda: 255 heads, 63 sectors, 1222 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 192 1542208+ 83 Linux native /dev/hda2 193 1015 6610747+ 83 Linux native /dev/hda3 1016 1023 6426083 Linux native /dev/hda4 1024 1222 1598467+ 5 Extended /dev/hda5 1024 1029 48163+ 70 DiskSecure Multi-Boot /dev/hda6 1030 1222 1550241 83 Linux native ** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ ---UNSUBSCRIBE--- mailto:[EMAIL PROTECTED]?subject=cmd:unsubscribe UNSUBSCRIBE DIGEST-- Use above but add DIGEST to the subject line... **
