When chainloading one pxelinux from another (e.g., chainloading from say pxelinux 4.07 to pxelinux 6.02), can one pass parameters or somehow control the root directory and/or server IP address? Here's the need: we have a loaded-up PXE server working great under 4.07, and I'm not prepared to just switch the entire setup to a newer version of pxelinux, too many folks depending on a

When I DHCP boot to lpxelinux.0 6.02, and then pxechn.c32 back to lpxelinux.0 6.02 with the http

In fact, this might allow us to install an automatic 'http' prefix on all subsequent requests, to avoid slow tftp --- or is that a bad idea, and/or is there a way to default all transfers to http without using pxechn and without prefixing

chain.c32 of SYSLINUX 3.82 does set the boot drive passed to the DL register to 0x80 and not to the boot drive (CD-drive). This can be a problem if you want to chainload grldr (grub4dos bootloader) from a CD and if you want to let grldr search for its menu.lst file on the CD.

My thumbdrive w/Syslinux and memdisk doesn't work on my Thinkpad laptop. But the thumbdrive does work on desktop platforms. And .. if i use Grub4dos with Syslinux .. it works on the Thinkpad Laptop. Any assistance would be greately appreciated! Thanks! <<john>> ____________________________________________________________________________________ Access over 1 million songs

I have a USB disk with syslinux files installed in /boot/syslinux, and the bootloader is installed into MBR or VBR I then extracted a *.iso file which uses syslinux as the bootloader, into root dir of the disk. The iso file contains a rescue OS or an OS installer. Now I got the directory /isolinux with files isolinux.bin and isolinux.cfg in this folder I can now boot into syslinux, but *what to

Thanks for responses. I use GRUB as my bootloader in my hard disk now. I have a Windows in sda1, Ubuntu in sda3. If I want to install extlinux to boot Ubuntu, should I follow the steps below? 1. in Ubuntu, go to extlinux folder, run command ./extlinux --install /boot 2. create an extlinux.conf in/boot 3. cd ../mbr 4. cat mbr.bin > /dev/sda (or use dd if=mbr.bin of=/dev/sda bs=404 count=1)

First let me say I'm really excited about the possibility of dynamic menu creation over http using php. When this is stable it will make maintinging some of our pxelinux infrastructure much easier. Id like to thank all involved; I'm really looking forward to the gpxe intigration. After hpa's announment for 3.70pre7 I begain testing. I dropped the new gpxelinux.0 and new c32 modules

Dear gentlemen, here goes the documentation fix I was talking about :-) The Wiki page on PXElinux, specifically the chapter on UEFI at the end of that page: https://wiki.syslinux.org/wiki/index.php?title=PXELINUX#UEFI ...contains a few examples of ISC DHCPd configuration. The stumbling block for me was the syntax of these "if" scopes: if option architecture-type = 9 { filename

Good day to all. Since we've adopted Gary Tong's and Bart Lagerweij's ElTorito.sys (now modified by H. Peter Anvin and tiny changes from myself), I'd appreciate if anyone with more El Torito experience might criticize my comments below and advise as to how they might be wrong. Some of it is off-topic GRUB4DOS detail; safe to ignore. A bit of history: FDUBCD ("FreeDOS

Hi It would be pretty useful to have syslinux in linux kernel format so it can be chainloaded easy and directly by other bootloaders such as grub4dos. related topics: http://www.boot-land.net/forums/index.php?showtopic=7013 http://www.boot-land.net/forums/index.php?s=&showtopic=6119&view=findpost&p=59236

Try using pxechn.c32 from the same version that you are booting with (6.04..., + libutil.c32 +

Hi syslinux experts, So, I have a pxe boot tree that looks something like this: /menu.cfg /linux /ubuntu /amd64 /meerkat (contains a mirror of the netboot ubuntu image) If I set the following in the appropriate stanza of my dhcpd.conf (for isc dhcpd v3), I can boot the ubuntu installer: filename "linux/ubuntu/amd64/meerkat/pxelinux.0"; next-server <tftp_server_ip>; I would
