We are attempting to setup an automated system to build some Linux systems. We have utilised the PXELINUX bootloader after encountering the PXE 512Kb limit with bootp. We now have another issue which you may have already run into. In the DHCP configuration we specify pxelinux.0 as the bootfile, this works reasonable well, we call the Redhat vmlinuz and initrd.img files within the pxelinux.cfg/config file and the installation begins as expected. We would like to have a non-interactive installation using the Kickstart mechanism to provide the responses, the issue is that the installer exp...

Hi everybody Attached you will find a file pxe.mnu (encoded with mime). It is PXE menu file created by 3COM MBA IMGEdit.exe tool. It is very strange since: 1) When I point DHCP bootfile to this file it loads with no problem and the menu is displayed. 2) When I point DHCP bootfile to pxelinux.0 and in pxelinux.cfg I put the command "KERNEL pxe.mnu" then system hangs. I wonder why this happens. Can anybody help me? Behrad --- Content-Type: application/octet-stream...

...want to support that too. So I've been using syslinux V6.03 to create usb sticks and harddisks to allow both bios and uefi boot which works fine.

Gene, As it happened I started working on this again just as you mailed me. It appears that PXE-E99 may also be related to MTFTP part of the PXE spec. IBM also says it has something to do with jumbo frames. I tried setting PXE.mtcp-ip to 0.0.0.0 to disable it but still no joy. The bootfile size shows up as zero because that relates to "option boot-size" in dhcp and doesn't seem to be the problem I've already fired up wireshark and had a look, and the tftp was the nas, so I'll move it over to the linux box to get the traffic. The ideas I have now to fix is to t...

hello, I have a problem about pxe booting. I have two isolated machines, one(server) has got dhcp and tftp servers working correctly ( I am pretty confident with this). The other machine (client) using floopy to boot with pxe-request. The problem is, the client cannot get the bootfile("/tftpboot/pxelinux.0"), it always report no boot filename found. I also found the IP address, which server assign to client, is also refused by client, since the "discover" process keeps running. I guess it is possible because I dont have "pxe-boot server" working p...

Well, googling has failed me. We've got a pxeboot setup, but we keep getting, in the logs, parse_option_buffer: malformed option dhcp.bootfile-name (code 67): option length exceeds option buffer length. This is CentOS 6.2 The section for those machines that can pxeboot is: group { allow booting; allow bootp; filename "pxelinux.0"; option dhcp.bootfile-name "pxelinux.0"; (I added this,...

Yes, you are missing these options in the DHCP server: 66 'Boot Server Host Name' (the tftp server IP) 67 'Bootfile Name' (pxelinux.0) -----Original Message----- From: Pierre VIALLET [mailto:pvt at auvitran.com] Sent: Wednesday, February 12, 2003 10:18 AM To: syslinux at zytor.com Subject: [syslinux] PXE boot from Windows XP Hi, I want to boot a VIA EPIA Motherboard from a Windows XP OS.

The receiver MUST NOT require that a trailing null be included in the data. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ In the case of some variable-length options the length field is a constant but must still be specified. So if I specify Bootfile name (option 67), frequently that's the last real DHCP option. Thus the next byte is the DHCP "end option" aka 255. The IBA code mistakenly parses this as "/boot/efi.x64/syslinux.efi^X", where ^X is a char with value 0xFF (255). It requests this filename from the TFTP s...

...y short time. What about implementing some sort of delay in the display format. Another great feature would be to support supplying the Default kernel options through the extended PXE tags. I wrote my own PXE server which provides the extended tags to the PXE client and I would like to specify the bootfile there. Moreover I would be happy to see a possibility to pass through custom PXE options. The only difficulty I see is how to get them into the operating system environment. (In my case DOS) Can RAM-Disk images be accessed before they are booted? If yes an init-file could be written to the ram-di...
