linux boot from sdhc card?
 
This is a sanity check because I am pretty wigged out at the moment.

Has anyone put linux on an sdhc card and booted?

my asus u81 will not see the sdhc card in POST.

I can read/write to the sdhc card from my SLAX booted
from usb.

I just busted a usb drive because it was sticking out. so I am eager to put linux on the sdhc card to minimize the chances of that happening again.

Thanks

I frequently have done this - the issue is that the BIOS must support booting from SD. Not all machines support this. If your particular machine does not support it, you will need to boot from CD/USB or from some other source.

use plop bootmanager "plpbt" or "plpbt.bin"
it doesnt install, just boots usb's, etc

here is link to one I use

plpbt> LINK

place that little exeutable on a partition on your hd, in a boot folder, wherever

add this entry to yuor menu.lst

Quote:

title Plop
root (hdx,x)
kernel /boot/plpbt
and it will boot your card too

if you wanna have a livecd that includes many utilities besides plop
get my ThorsHammer livecd/usb/hd

I appreciate your point - but if you are using that, you're not really booting from SD :D

and the difference is?

I dont care how it boots or who/what boots it as long as it boots

so, I dont even see your point?

Not to pick nits or derail the conversation, but if you have a system that's un-bootable due to a damaged hard drive, or one that is using full disk encryption that is currently inaccessible, or even one where you don't want to modify the existing hard drive, booting from SD by modifying the existing boot loader would be a problem.

It actually does matter on occasion. For example, we have laptops at my office that use a form of full disk encryption. When many of the drives got damaged due to a bad update, they were rendered completely unbootable. While we waited for that IT department to get around to fixing them, we were up and running via PenDriveLinux on a motley combination of SD cards and USB drives.
