USB boot, no boot, boot, no boot, boot, no boot

Dear all

This is driving me NUTS ....

My slax sometimes boots and sometimes I get the Searching for livecd.sgn --> failed ctrl+alt+del problem when I boot with USB ... It is completely unpredictable ... sometimes it does sometimes it doesn't ... I am lossing my mind here.............

I have bought 4 (!!!!) Different USB flash drives with different capacities ( 1GB, 2GB, 4GB, 8GB) respectively

they are all from different manufacturers, LG, SuperTalent, Toshiba, Generic...

I am also using 4 (!?) different computers .. 1 Dell D630 laptop x2, 1 Hi-Grade M6600 x1, Laptop, 1 AMD NF4 x2 desktop, 1 INTEL core 2 Desktop (Foxconn mobo I think).

They all exhibit the same behaviour .. ALL USB drives with ALL COMPUTERS do the same thing... they boot once, then they do not boot 10 times, then they boot 5 times, then they do not boot 15 times.. and I am not even changing anything ... I am just testing if they boot.. I have been at it for 3 days now.. I am losing it.!!!!

PLEASE DOES ANYONE HAVE ANY SUGGESTIONS ????????? ( I am not shouting I am begging )



thank you

Hi

All machines have had their BIOS updated to the latest available.

Yeah, why not ignore BIOS USB Boot support completely
and just give the 'PLoP' bootable diskette a try instead?...

Guys

I prefer the USB approach... when it works it is very very very convenient to me. Trust me I need it.

The problem is that I get one happy moment and then it does not work again for hours. Then as if by magic

the same USB stick will work on the same machine it had not been for hours. I am not changing anything for God's sake I am not... I just plug in turn on, plug in turn on plug in turn on, and it is doing whatever it wants with all possible combinations of machine usb stick... I am really really lost.. .

************ I have followed instructions to the letter to create the USB drives, and it is proven by the fact that they work once every fifteen times or so

i initially had this problem as well. was stunned and pissed off for a little while. until...

it appears that...if u run do the bootinst.sh or bootinst.bat with your USB stick in a particular slot, it will only work when you try booting from that one. so if it's /dev/sda when u do run bootinst.* and you put it into another slot while booting, it gives that error.

try this:
whichever computer u try to USB boot from, put the USB key in the same slot. so you'd need to know which one is the 'first' USB slot if you used that while running bootinst (sda), same goes for using the 2nd slot, etc.

unfortunately, root=/dev/ram0 prevents you from doing something like...
edit the 'root=' part of it to point to /dev/sd[a,b,c,d] as appropriate. (or trial and error if you aren't sure)

You could try formatting a USB drive with a Linux file system, such as Ext3. Then use liloinst.sh to setup the Lilo boot loader.

have you tried usb boot by using slax 6.0.8 or slax 6.0.7 ?
(note that some of those computers may not be recognised fully on 6.0.7 )

Pretty frustrating. Linux relationship with usb still seems in the primitive stages.

Clarify what you mean by not booting? Is it that your bios only recognizes the stick occasionally, or does it get past the dots [loading vmlinuz and initrd.gz phase] or is it somewhere beyond that it fails?

If it's my first guess, then it wouldn't be slax itself at fault -- bios in the earliest phase of booting, then syslinux is what loads kernel and initrd. Once past the dots, it's slax.

One of my machines here has a cmos setup item that mentions thumbdrives, another that mentions dos under the usb options.

Apologies guys

the USB sticks are all recognised by the BIOS'es and all computers begin the boot sequence ..then they all (with all 4 machines) stop when looking for the livecd.sgn ... God knows.

*******
Searching for livecd.sgn --> failed ctrl+alt+del ..that is the point where the problem occurs...

Someone should clarify this. Isn't livecd.sgn just a little file that just sits in slax's root? I think if root is not foud then livecd.sgn is not foud either. Something is wrong with finding root. Are your thumbdrives formatted with ntfs or fat32?

reply
Yes I understand all that, but I don't understand why... I mean all my USB sticks are formated with FAT32

they are created exactly how the instructions say, and it works because all of them WILL boot occasionally but will NOT boot consistently !!!!!!!!!!!!!!!!!!!!!!! That is the main problem and what drives me mad !!!!!!!

I mean if it boots at 10:15am and then I shut down with no changes and power up again WHY WILL IT NOT BOOT AT 10:17am ?????????????????????????????????

Do you happen to have a directory somewhere on your hard drive called "slax" ?

Hi

thanks for the response... No I do not currently have a directory called slax anywhere in my hard drive currently

in any of my 4 machines , I did make a slax directory in one machine (the dell laptop ) following the console error message advice, but when I saw it did not solve the problem I removed it completely..

the other 3 machines exhibiting the same pattern have never had a slax directory in their hard drives

Ok can you identify which device you USB flash drive is (/dev/sdb1, /dev/sdc1, etc)? If you can (bear with me), try to keep booting your slax using the "from=" cheat code. When you boot up and get the menu with the different ways to boot slax (GUI, Always fresh, Text only, etc), hit the TAB key and you get the boot parameters at the bottom. Append to the end of the line "from=/dev/sdXY" where sdbXY is what was identified as your usb flash drive (/dev/sdb1, /dev/sdc1, etc). That should force it to look directly at the usb flash drive and not search every single device for the file.

If you keep booting that way and STILL get the problem, then something is wrong with the files on the keys somehow. If you had used the tgz to make the usb keys, I suggest getting the ISO and extracting the boot/ and slax/ directories from it then run the bootinst.bat.

This seems to have worked for at least the Dell laptop at the moment and the super talent usb stick, I have booted the others this way and they don't seem to work... I will re-install slax on the other usb sticks and see if that approach works.

When you say I should try the iso version, you mean the one available for the CD version ? is there an Iso for USB ? I am not sure I found an Iso for usb's

Thanks for the help so far

Yes I mean the one available for the CD version. Get a ISO extractor or in slax mount -o loop the iso file to some empty directory and copy the boot/ and slax/ files out to the USB key, then run the bootinst programs (bootinst.bat if in windows, bootinst.sh if in slax).

This smells to me like a timing problem -- there's no good way to explain a system that boots OK once and not the next time as a corruption issue.

Just throwing a wild suggestion, try adding the 'debug' cheatcode -- will make booting run much slower.

I also like the test suggestion to use an explicit from=/mnt/sda1/slax cheatcode -- which I think bypasses the routines that search for a /slax directory. I'd also use a unique name like from=/mnt/sda1/slax609.

If you still have the .iso file on your harddisk, you could also try booting with the usbstick and give it a from=/mnt/hda1/slax.iso cheatcode. (and in all cases fix the names I've used to suit your machine)

I have noticed one thing about USB in Slackware12.2, maybe it sneaked it's way to slax.

I have a Eee701-4g-Surf and i use a flashdrive to unlock the encrypted root. At least on Eee, if I stick the drive in one of the right side ports, it becomes /dev/sdc, but if i stick it into one on the left, it becomes /dev/sdb. It's because the Eee has SD reader and it sometimes appears as /dev/sdb and other times it appears as /dev/sdc. I'm guessing you might have some card readers or other USB hardware that interferes with booting from USB. Just a guess.

Guys

As I said before the from=/dev/sdx works if one manages to identify how the usb drive is identified.. at least one of the 4 I have..

I was too busy to check the other usb drives on the other machines, I will try to do so within the next two days.

any ideas why this is happening and how one can go about solving this permanently ?

It is strange. 4 machines with 4 thumbdrives for one guy when hundreds of other people with one pc and one thumdrive have no problems. Maybe the download is corrupt or maybe you use some module on all four of them that messes with slax. Try downloading again and reinstalling.

hey guys

i'm facing the same problem exactly i have one usb with slax 6.09 it works once every too many times. i'm trying on a laptop and desktop machine hoth having the same problem and both working some times.

if i choose the always fresh option there are no problems at all on the laptop or the desktop.

i used to have salx 6.07 for very long time without any problem.

I'm beginning to wonder if the posixvol implementation for 607 and 609 are the same...
