similar to: syslinux: localboot error

Hello everyone, I use syslinux to make bootable USB sticks. I would like to offer the choice, right at the beginning, to either continue booting from the USB stick, or to boot as usual from the hard disk. Is this psossible to do with syslinux ? Thanks, Al

I just tried to boot extlinux off of /dev/sdb and use the option localboot 0x80. I was hoping to see syslinux for the second time as the system loaded the master boot rec from /dev/sda. Why is this option only in pxelinux and isolinux? Nicholas A. Schembri State College PA USA

Hi, I'm trying to get the LOCALBOOT option to work with syslinux. I have a bootable USB that boots using syslinux and when ever I select the localboot label it says that it could not find the kernel image. This is my syslinux set up LABEL start localboot 0x80 and when I type "start" at the boot prompt this is what I get back "Could not find kernel image: start" Is

A bug in command localboot was introduced in version 6.03. This bug was created because of inserting memsets in core/localboot.c. The third memset before /* Read one sector */ clears the field ireg.edx, which was assigned earlier and is required for subsequent __intcall0x13. So localboot type works as localboot 0. I think, this third memset in core/localboot.c is useless and excessive.

I have been using PXELINUX, with "LOCALBOOT 0" when wanting to boot from disk, for many years. Now on new Dell Optiplex 990 machines, PXE boot with "LOCALBOOT 0" hangs after message Booting from local disk... without the expected "Exiting PXE" message. I tried "LOCALBOOT -1" and some other values also, none seemed to work. I tested SYSLINUX 4.04.

I am using the following simple menu and have noticed that items at the bottom are dropping off. I seem to be limited to 12 items. Is there a limit to how many items can be on the simple menu? default pxelinux.cfg/menu.c32 prompt 0 MENU TITLE UWSP PXE Boot Menu # TIMEOUT 200 LABEL bartpe MENU LABEL Build 12 KERNEL /STARTROM.0 APPEND keeppxe LABEL 11dnet MENU LABEL Build 11DNET beta

What about "chain.c32 hd1" or "chain.c32 hd1 swap"? Jonas Keidel <jonas at jonas-keidel.de> wrote: >2013/8/5 Jonas Keidel <jonas at jonas-keidel.de> > >> >> >> 2013/8/5 H. Peter Anvin <hpa at zytor.com> >> >>> On 08/05/2013 07:04 AM, Jonas Keidel wrote: >>> >>> > >>> > So i've also

pxelinux, when given a localboot=... option, will try to boot next bios device itself. The problem is it takes next BIOS device by BIOS order of enumeration. That has no connection with the boot order defined in BIOS. Since a user cannot control BIOS enumeration but can control the boot order, there is no way one can force a desired next device for local boot with pxelinux. In general, you

Ive got a soekris 4801 on which Ive used pxelinux... its bios is set to go to pxeboot 1st, then localboot. Ive got: label bootlocal MENU label ^9 Boot Local localboot 0 # timeout 80 # TOTALTIMEOUT 9000 but using hangs: Booting from local disk... PXE-M0F: Exiting MacPhyter PXE ROM. then nothing. the same compact flash image works fine when boot order is 80 1st, or

The idea is to boot a disk in an mbr fashion while using the GPT (not filesystem) label to detect the disk. That is useful when you use grub2 & gpt. I was in case where my nodes (100s) have 8 disks each and no guarantee of which disk is "bootable" in the disk. This way I can tell "please boot the disk that have one partition labelled "xyz"". So nothing related

Hi! A friend of mine has tried a PXE floppy (build from the new etherboot 5.3.12) to load PXELINUX.0; a menu voice of the pxelinux.cfg use the LOCALBOOT statement. Selecting this statement, the PC retry to boot from the floppy... is this normal? The user expected that LOCALBOOT would have tried the NEXT boot device (ie CDROM or HD), not the FIRST boot device (the floppy)... (note: this has
