increasing ramdisk

[Bernhard Helmes]

A beautifull day Michael,

i would like to increase the ramdisk in order to speed up my program.
I tried
boot: live ramdisk_size=4000000

i have 8Gb ram and would like to use 4Gb for the ramdisk. But it does not go.
Any idea ?

Hi Bernhard,

As you note, you need to use the ramdisk_size=x cheatcode, where x is desired size in KB. For example, to have 500MB for /home and a Spanish keyboard, I can type

live keyb=es ramdisk_size=500000

at the boot prompt. This is a good question, since the default is too small for serious work (note however that for serious work it's probably better to use hard disk space for /home, so that it gets permanently stored). I'm going to add a link to this post on the homepage.

Now, why this doesn't work for you? Hmm. Maybe there is a limitation on the size of ramdisks? Are you using the 64 bit version (recommended)?

Thanks, M.

Hello Michael,

i used the version 1.5 and could only use 40MB ramdisk.
i made an update to 1.72 and could make a ramdisk with 4Gbyte

Hi Bernhard,

I am a student of M.Sc. Computer Science from a Third world country. I need to submit a Project Work on "Implementation of  Big RAMDisk(>64 MB)" for academic degree. But I am totally hopeless after searching on web because there is not enough information on this issue.

But after reading your post I have some hope now. If you please tell me how can I implement a RAMDisk greater than 64 MB size then it will be very helpful for me to complete my degree.

So, please please help me.

NB: I am using the code from "http://www.codeguru.com/cpp/w-p/system/devicedriverdevelopment/article.php/c5789" and the file name is "RAMDisk_src.zip"

Thanks
Imran

Hi,

it depends on the operating system. You can use the cheatcodes for knoppix, kanotix, pelicanhpc and some other linux operating systems.
For example you give before the booting the cheatcode for pelican hpc
boot: live ramdisk_size=400000
it is easy.
For windows do not ask me, sorry.
Best regards and good success
Bernhard
