Re: Booting Off SD Cards

i don't think that's such a good idea since the sd card is significantly slower than a usb drive
but you could to dump the iso on a sd card the same way you do it on a usb i suppose

Re: Booting Off SD Cards

Depends on your BIOS - some support booting from SD as though it were USB, some don't.  If yours doesn't support it, you're SOL (possible BIOS flashes notwithstanding).  If you have a USB SD card reader...

Re: Booting Off SD Cards

AFAIK every new computer (1~2 years old and newer) can boot from an SD-card. I know that mine can, I used to run #! 9.04 on one. The approach to making one is the same as making a liveUSB.

Re: Booting Off SD Cards

thats what i figured everyone, i just dont think my bios support direct SD card boot, id have to do it through a USB reader. And @ali SD cards i think are the same as thumbdrives as they are both flash memory types

Re: Booting Off SD Cards

@Unia:  I believe most versions of the Asus BIOS support booting directly from the SD slot; I know my Dell Mini doesn't, but I can throw a microSD card in a USB adapter and use that as a LiveUSB.

Re: Booting Off SD Cards

I am currently running #! from a SD card and have been following your tips and tricks to tweak its performance, the OS runs very well and I can say better than Ubuntu installed on my HD. The boot times and shutdown times have been somewhat slow, 36s to boot and 27s to shutdown. After installing readahead-fedora as explained here http://crunchbanglinux.org/forums/topic … el/page/4/ and following crunchmic's advice of switching off tty and replace all statements with "wait" by "once" in my inittab as described here http://crunchbanglinux.org/forums/topic … p-my-boot/ along with replacing getty with mingetty and finally disabling unnecessary daemons from startup as described by Unia here http://crunchbanglinux.org/forums/topic … -services/ I must say it runs extremely well, bootup times are at 33s and shutdown at 20s, I run ssvnc as well as virtualbox and am extremely pleased ... so much so that I have cloned my 16GB SD card expecting my friends/colleagues to be asking for me to install #! on their netbooks.

aside: a couple of friends and all colleagues at work are running HP Mini's. with 1GB of ram

speaking of ram the system runs at 61 MB at startup
680 MB running virtualbox (having assigned 400MB to XP)
130 MB running all apps (not all at once) e.g Chrome

ty for this guys

edit: figured I'd post a screenshot
