I am using legacy boot which is being deployed using IPXE.
I can currently boot perfectly into devices with sda disks from IPXE using
sanboot --no-describe 0x80
However, this same command does not work for booting nvme disks form IPXE.
Looking up on IPXE documentations did not give any information on this.
Hi All,
Our Red Hat OpenShift/Kubernetes servers appear to have been upgraded over the last few days and iPXE started giving me the following error. I've pulled the latest sources and compiled with DEBUG=tls:1 and disabled OCSP.
Here's a screen dump of the error with tls debug enabled:
Guys, could you give me please a simple example that shows how to boot 4GB ISO-image via SMB/CIFS protocol because I use local windows network? My ISO contains "EFI" folder and bootmgr file.
Thank you!
P.S. If it is not possible to use SMB/CIFS for some reasons could you please give an example of booting ISO via HTTP then?
I just found out about iPXE when I was working on a project relating to AWS.
Basically I was able to boot from the test chain from the iPXE page. I looked around youtube and I see this have been around a while.
Is there a list of available repos I can play with? I'm partial to Linux-Lite.
Or do you recommend I go through the whole documentation, write my own script.
The thing is, I'm not interested in actually storing any of this in a web service. The idea is I want something quick to boot into (like the test) in my virtualbox or vmware image inside GNS3.
i have an "Fujitsu Futro S550-2" and i dont if its possible or not to burn a compiled "10ec8168.rom" into the PXE flash part of the onboard device: "Realtek 10ec:8168" because i think the part of PXE for this device resist into the bios or ?Image may be NSFW. Clik here to view.
I`ve got two Panasonic Toughbooks CF-M34 mark 1, as out company would have thrown them away elsewise.
Since they are in perfect state still, I decided to dispose them myself in person. ; )
The Toughbooks unfortunately allow only to boot from A: or C:. Also ths thing has no ethernet port, same goes for the docking station, that I aso have.
Okay, so far so good.. I can boot from floppy, which means I could iPXE boot some boot media, so I thought, but since this hardware has no ethernet port, I need to use the PCMCIA port. Now I have three PCMCIA LAN cards.. a Highscreen one, a Xircom one and a 3Com. According to the [iPXE device list] the 3Com and Xircom cards are the most promising ones.
Unfortunately none of the cards does work with the latest iPXE boot image. :/
Question is, is there a way to enable PCMCIA support and make a 3Com 3C589D Combo card work with iPXE?
I`d like to boot CloneZilla first, to image the current HDD status, and then, after this, I`d install either [ArcaOS] or OS/2 Warp. - Maybe even Windows 2000.

Test environment:
ServerPC: windows server 2012 iscsi target + tftp32 + latest ipxe.efi / snponly.efi
ClientPC : 1000M PCI-E NIC with UEFI network boot enabled ,local harddisk has removed.
After ClientPC boot into ipxe shell , I type
dhcp --> set keep-san 1 -> sanboot iscsi:10.10.10.253::::iqn.2019.com.test:gpt in shell , then the clientPC begin load OS image, but very very slowly, it takes about 3 - 5 minutes before the windows boot animation logo appeared.
and at this time, I found the wintarget service in server side has crashed, and once I restart the wintarget servive, it crashed immediately , after crash -> restart for 10 - 20 times , the clientPC can successfully boot into windows desktop.
I tried snponly.efi , and tried another PC with diffrent NIC, the resule always same. So I guess this is not a network or NIC problem, it maybe the ipxe send a wrong scsi command to iscsi target, and caused the target crash.
So I fetched the lates IPXE source ,and compiled with DEBUG=iscsi,scsi,efi_block:2, and enable syslog, then I replace ipxe.efi in server side, and reboot the clientPC.
once the log line " <6>ipxe: EFIBLK 0x80 read LBA 0x004a5988 to 0x24c5000+0x014c2600 10.10.10.1 13/04 00:05:37.685 " appeared , the wintarget crashed .
from the source , the 0x014c2600 in the log line means read size, I don't understand why the system try to read 0x014c2600 bytes (21M) data in one scsi IO.
It seems there is a bug in ipxe efi block io?
(This boot slow problem and large size scsi read request won't appear in bios mode iscsi boot, only uefi)
any one can help? thanks very much.
I simply add code :
if (len >= 0x1000000)
{
return EFI_BAD_BUFFER_SIZE;
}
in the function efi_block_io_read (efi_block.c) , the client can successfully boot in 30 - 40 seconds, and the target has not crash.
But this is not a good solution, we need to found the reason why the len argument is so big.
The exact list of supported cipher suites is
RSA_WITH_AES_256_CBC_SHA256,
RSA_WITH_AES_128_CBC_SHA256,
RSA_WITH_AES_256_CBC_SHA, and
RSA_WITH_AES_128_CBC_SHA.
but RSA_WITH_AES_xxx_CBC_SHAxx now is considered insecure algorithm, can ipxe support the ECDHE cipher suites?
i have 2 NIC's in my pc, one onboard and a quad port one, i want to pxe boot from the onboad device
but the quad port card comes on initialising devices first. so i dont want to wait for all 0-3 nics (net0/net1/net2/net3) of this quad port card getting timeout and then ipxe tries to boot from the onboard lan

how can i skip the devices net0-3, before (net4...the real pxe boot device) without pressing every time ctrl+c ? i mean how can i directly boot from net4 ?
thanks
I am having issue with one Dell model to image, keep getting the following error.

I'm having some problems getting netboot to work on a UEFI based arm 64-bit system (Ampere Computing eMAG). Right now I'm just trying to get Ubuntu to work.
My assumption is that the linux image is not EFI compatible. In the Ubuntu path I'm using there's a netbootaa64.efi file, which (and I have limited experience) looks like the right netboot binary for me to use. But I'm not quite sure how to use iPXE in this way.
Some more background:
Ubuntu netbootaa64.efi path: here
iPXE Version: 1.0.255+
Provisioning Platform: Packet
HW Platform: Ampere Computing eMAG (c2.large.arm on Packet)
I did some tests trying to chain load the efi file, something like:
Code:
#!ipxe
chain http://path/to/repo/netbootaa64.efi
The error above goes away and the efi file is downloaded, but I get dropped straight into the grub shell with no apparently filesystem*.
*ls in the grub shell gives me (hd0) with no partitions listed. ls (hd0)/ gives me a 'no filesystem found' error.
I also found some threads that reference using the
Code:
kernelefi
or
Code:
initrdefi
commands in the iPXE script, but those commands are not found and give an error when the script runs.
Anyone have some pointers to how I can get a netboot of Ubuntu working through iPXE on an aarch64 UEFI based system? Really stuck on this one.
I'm currently doing volunteer work for a school that has a limited budget. They have about 40 Raspberry Pi 3B+ units, 20 Dell PCs, and 10 HP PCs. All Dell units are the same as each other and all HP units are the same as each other (i.e. homogeneous configuration). The school doesn't have the money to replace the hard disks in all the units (all PCs and Pis were donated with no persistent storage device), and they just need to boot Ubuntu or Raspian to run a browser, educational games, etc.
Is it possible with iPXE to, on the client PCs, at boot time:
Detect the system architecture (i.e. arm versus Intel) so that it auto-boots a specific boot image without user intervention (i.e. Ubuntu versus Raspian).
Detect differences in hardware (i.e. so the Intel units can check before booting, what manufacturer/model/make of network card, HDD if present, hardware, etc. (we'd like to use a different boot image for the Dell versus HP machines, as we may be able to get a donation of HDD/SDD units for the HP units, in which case, they would still boot via iPXE, but the persistent storage could be used to hold onto kids' files, drawings, animations, etc.).
Hello everyone.
I have my ipxe server that works great.
I just have a problem when I want to start my client computers on a winpe image in tftp.
I have to have 2 configurations for legacy positions and for uefi posts. For uefi, I put "kernel wimboot" then "initrd BCD"... For legacy, I have to put "kernel wimboot wimboot" then "initrd BCD BCD" ...
Is it possible to have the same config for all positions in legacy or uefi? Thank you in advance
