5GB in virtual ram with DVD Knoppix LiveDVD

A remastered DVD Knoppix V3.4 with kernel 2.6.3 has been modified to enable booting TORAM .  The DVD has 4.9Gb of program material.

The technique to modify the DVD to enable TORAM (doesn't load to ram natively, only loads from DVD disc) involves using the script from the KnoppixLiveCD which does load to ram if 1GB of ram is available.  ( Swap is also a possible with the CD version)

I modified the minirt26 scriptof the CD to allow 3GB of TORAM capability and replaced the DVD script of minirt26 with the modified CD script.

The DVD is enhanced by a 2GB swap file provided by a USB hdd having a swap partition of 2GB.  This swap was setup by QTParted on a 30GB hdd in USB sda1.  Usb 2.0 was enabled in isolinux.cfg for the dvd burn by adding the option...ehci-hcd.o to the USB option list.

The dvd remastered with the CD minirt26 boots to desktop in under ten minutes and the system resource monitor utility reports 5GB of memory + swap.

A 1GB video file loaded to desktop in 50secs. and played without indication of hdd activity.

The remastered..remaster was burned with a Sony DRU530 at 4x+RW.

My system is athlon1900+ with an asus a7v333 with bios 1006.

This is a large lollipop!!!!

Re: 5GB in virtual ram with DVD Knoppix LiveDVD

The dvd boots to desktop in 8 minutes.

Trial of..     fromhd toram..... produced a 35mb/s install of the Knoppix files but failed to reach desktop.

Working on the problem.

Re: 5GB in virtual ram with DVD Knoppix LiveDVD

The Knoppix3.4remastered LiveDVD has been modified in linuxrc to enable ..toram.. option to boot.

Original script had only allowed 800MB of memory size, which when increased to 3000MB enabled the Live DVD to boot.

Subsequent entry into hda3 with tohd option enabled the eventual boot of ....fromhd  toram...This produced a load time of one and a half minutes to kde desktop.

The system resource utility confirmed the loading of 2.1Gb into a 3GB memory limit.

My system is athlon 1900+ with 3GB of 2100SDRAM.
