H. Peter, Do you still work at Intel? Any pull with Intel's NIC F/W team? Ask them to "Respect the RFC!" (Like Cartman -- "Respect My Authority!") That would be the best solution. :-) But I know I work for a hardware vendor and I have *zero* pull with any internal firmware team. Spike > Date: Tue, 18 Mar 2014 12:02:54 -0700 > From: "H.

All, I was excited to hear about EFI boot support in pxelinux >= 6.00. So I tried it. Not working. I've tried 6.02 (from source), 6.02 (from RPM), early 6.03 (from RPM) and even pulled/compiled latest source from git. 6.0.3-pre7. No love. My boot client can boot/image fine in legacy PXE mode. My dhcpd.conf looks like this: # In initial DHCP DISCOVER packet, PXE client sets option

All, I realize this is not strictly a PXELINUX question. So I hope you'll indulge me; hopefully some of these PXELINUX experts have seen this before. And can tell me what I'm doing wrong. Or confirm my suspicions. I have a test lab server at work. Split config. The network team manages the DHCP servers, points to our TFTP server. Test subnet has 3 DHCP pools. BIOS PXE, UEFI PXE and

First, THANKS! The SYSLINUX/PXELINUX s/w and docs are great. I have been able to set up a working server for PXE boot in very little time, using our existing Win2k DHCP server and a Red Hat 7.2 Linux server for tftp, etc... It took very little time (compared to an earlier effort 4 months ago.....) and the pxelinux/menu/memdisk environment is great for us. The environment seems to support PXE

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

Gene, Where did you find the precompiled binaries for syslinux 6.03-pre7? Actually, I'm interested in the pre-compiled binaries for syslinux 6.03-pre6. I went out to kernel.org, but the latest they have is 6.02. Which appears to have an endian problem in its TFTP client code (when syslinux.efi tries to connect to the TFTP server, attempts to connect to UDP port 17664 instead of 69).

Hello. In my case I can successfully boot up my Thinkpad X32, but the same configuration doesn't work for my desktop computer with Intel network card, with Intel Boot Agent 2.2 DHCP server is 10.0.0.1, tftpd (used tftp-hpa) runs on 10.0.0.32. netstat told me the daemon listen to 69 UDP port just fine. running tftp in commandline also shows it works (retrieve pxelinux.0 less then 1 second).

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

Gene, All good questions. Thanks for taking time to respond. You've given me great leads to follow up w/ DHCP appliance consultant. >filename being file.

Hi, I have a tftp client that sends out a tftp file request with an empty (but null terminated) filename. IMHO this is a bug, but I still need to be able to use TFTP with this client. Modifying the client is out of the question at this point. To deal with this situation I modified tftp-hpa in what I hope is an unobtrusive manner -- I basically modified the code to map "" filenames

Hey, I have a problem booting certain machines with pxelinux. I have pxelinux.0 in the root of my tftp server and dhcp pointing to the right location: # dhcpd.conf authoritative; option domain-name "example.net"; ddns-update-style none; default-lease-time 3600; max-lease-time 86400; subnet 10.0.0.0 netmask 255.255.255.0 { range 10.0.0.3 10.0.0.20; server-name

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

As subject says: With Intel PXE stack version 4.x (stack identifies itself in BIOS as IBA 4.0.x or 4.1.x), pxelinux' localboot option hangs instead of going to BIOS. This does not happen with older PXE stack. I have a feeling that the this broke somewhere in version 2.x - I *believe* 1.75 PXELINUX works fine - but haven't had a chance to try again. -alex

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
