Unable to open initramfs

May 10, 2019, 12:38 am

Hi, I'm having trouble with the initramfs I am using when booting in UEFI. The initramfs works when in legacy but when trying to run on UEFI the system it "failed to open file". Additional info for context: My goal is just to load the ramdisk image and not load to any storage device because I intend to test all storage devices by running destructive tools against them, hope that makes sense :-)

Here are the events leading up to failure:
1) Boot into ipxe with embed script:
#!ipxe

echo Will keep trying to get a valid DHCP address before loading the image
echo via http://x.x.x.x/ipxe/ipxe-usbnic.script
:retry
ifstat
ifconf -c dhcp || goto retry
chain http://x.x.x.x/api/ipxe/ipxe-usbnic.script

2) Loads the following from the ipxe-usbnic.script
#!ipxe
set mfg_data http://x.x.x.x/data
set mfg_releases http://x.x.x.x/releases
menu
item uut_os Boot the UUT Ramdisk Based OS (the default)

choose --default uut_os --timeout 10000 target && goto ${target}
:uut_os
set default_uut_os ${mfg_data}/uut-os/default
kernel ${default_uut_os}/vmlinuz console=ttyS0,11520 fastboot initrd=${default_uut_os}/initramfs.gz mfg_setup=${mfg_releases}/mfg/default/admin/uut_os/setup-after-boot.sh
initrd ${default_uut_os}/initramfs.gz
boot

:shell
shell
:exit
exit

It looks like it's able to download the images, but when trying to unpack the initramfs.gz it fails. Do I need to modify anything for UEFI? Thanks...any hints would be greatly appreciated.

Hi,
I see that the 'wd' driver supports SMC 83C790 ISA NICs. Is the 83C795 chip close enough to work as well?

Asix AX88179 USB to Ethernet Adapter

Hello,

I have previously had iPXE working on a Mellanox NIC, however during testing we noticed that iPXE was not working on our ASIX AX88179 USB Adapter.

I have seen the FAQ and other posts about this with workarounds however these are not working for me. The issue I am having is that as soon as the DHCP command is run in the iPXE shell and configures the ASIX adapter, iPXE no longer takes any input and I'm forced to reboot the system.

This issue has occurred when compiling ncm--ecm--axge.efi, axge.efi, and ipxe.efi.

If anyone has a method that has worked with this driver I would greatly appreciate it.

Thank you,
Max

Hi,

I have some Laptops with a Qualcomm Atheros AR8161 (PCI ID 1969:1091) ethernet controller.
I can't get iPXE (current git) to recognize these.
Is it unsupported or should I look for other errors with my setup?

iPxe, http, basic auth and login command in embed script and in menu script

I have the latest git veriosn of iPXE compiled from sources by myself.
There is login commands in 2 places - in embed script:
Code:
#!ipxe

ifconf || reboot
login || reboot
chain http://${username:uristring}:${password:uristring}@fqdn/folder/menu.ipxe

which is compiled in during make step, for example make bin/undionly.kpxe EMBED=script.ipxe

and in menu itself:
Code:
login
kernel http://${username:uristring}:${password:uristring}@fqdn/folder/folder1/wimboot
initrd http://${username:uristring}:${password:uristring}@fqdn/folder/folder1/BCD  BCD
.....

But 1 during first login command empty username and password is sent to Web server.
As following, Permission is denied.
I saw at its logs.
During second login is ok.
But if is to remove login command from embed script and specify exact user/password at http string all is ok.
That is:
Code:
#!ipxe

imgfree
ifconf || reboot
chain http://rightuser:rightpass@fqdn/folder/menu.ipxe

After that, login in menu works fine.

Is it right functioing by design ?

There is DOWNLOAD_PROTO_FILE option at xPxe sources.
Is it possible to map to memory or to load locally stored file such as menu, wimboot which are located for example in the same folder with undionly.kpxe to further chain and execute ?
Or from other local file system ?
That is: menu.pxe and then wimboot are mapped/loaded/chained from some /folder/folder1 and only afther that chain/kernel/initrd will use either http or nfs protocols.

Display bug with console/PNG feature

I'm using ipxe.efi compiled on Ubuntu (approximately one week ago).

When booting windows from an iscsi target (SANBOOT) the display is unreadable. I have traced the issue to the following command in my ipxe menu script -

console --picture ipxe.png

Commenting out this line removed the issue. Screenshots of the problem -

http://mistyprojects.co.uk/screenshots/2019.05.20_1.jpg

http://mistyprojects.co.uk/screenshots/2019.05.20_2.jpg

This bug/error was discovered when installing windows to an iscsi target by booting into WinPE (SANHOOK target and booting via wimboot) and running setup.exe. Stage 1 of setup (selecting the target disk and applying install.wim, etc) completed fine and the display was rendered properly. Following the reboot and starting stage 2 resulted in the display issue.

I lengthy thread I started on the reboot.pro forum documents my setup and this issue in much more detail -

http://reboot.pro/topic/22026-sanboot-wi...efi-system

Misty

P.s. let me know if there is anything I can do to try and trace the issue, or if any more details are required.

Hi,

Running into an issue where the first port of the first NIC goes missing. I see that the file path uses the correct adapter but then in ifstat its missing from the list.

Unfortunately I am inheriting this setup and I do not know how ipxe was compiled. Any ideas on why this occurring or how it can be fixed? Thank you in advance!

HP DL380 Gen10 Error: 0xc0000001

I have other hardware booting with the exact same setup. We are using MDT and chaining directly to MDTs litetouchpe image. Specifically on these HP DL380 gen10 servers we get an error:

BlInitializeLibrary failed 0xc0000001

Whats interesting is that the output between this server and a working server are nearly the same minus the memory addresses. I tried injecting HPs drivers into the PE image and that did not work, tried different BCD files that also did not work, also tried using copype and using the files it created and that did not work. Out of ideas at this point and that error is pretty not helpful :/

Thanks!

Hi,

is it possible with ipxe to skip the dhcp request each time on "Boot from LAN".
The Intel NIC has an flashrom in my pc, may possible to burn an ipxe-flash-rom into the rom from the card, but i dont know if it possible to skip the dhcp request and boot directly "from LAN", from an specified IP-Adress!?

Thanks a Lot.

"try to free memory without signature"

Hi All,

I have a bunch of identical machines that all happily iPXE boot except one, which gives me the "try to free memory without signature" when initializing devices.

The NIC that is PXE booting is an onboard Intel I210V, and intel boot agent GE 1.5.73, and i am not able to flash it with intel's bootutil (not supported).

The motherboards are all on identical BIOS versions, and set up with identical options (I've tried reflashing the BIOS). I'm booting in legacy mode as UEFI settings in the BIOS cause the machines (all of them) to POST extremely slowly.

In any case, does this mean this one machine's motherboard is borked? Anything I could try to fix this?

Thanks!

The following page focuses on SANBOOT - more specifically installing and then booting a Windows OS from an iSCSI Target running on a Windows Host OS - http://mistyprojects.co.uk/documents/iscsi-targets/

List of Windows Operating Systems that I was able to SANBOOT - http://mistyprojects.co.uk/documents/isc...ported.htm

iPXE was used in testing. EFI SANBOOT is not widely supported by Windows Target Software.

Chainload ipxe script via PXE

June 10, 2019, 6:20 pm

Hi, not even sure how to correctly title this thread.

Here is my working scenario.

I have an HTTP share that hosts an iPXE script, the same share also hosts the install files for esxi.

In the pxelinux.cfg foolder of my PXE server I have my config file, I use undionly.kpxe as my bootfile. This boot file has a small script to chain the pxe config file, and then in the PXE config I chainload (via HTTP) a ipxe script. This works 100%

Now some of my site have a firewall the will block HTTP traffic to overcome this I want to failback to tftp. I figured I could do something like the below in my undionly.kpxe embedded script

Code:
#!ipxe

dhcp
chain http://${next-server}/pxelinux.cfg/macaddress || chain tftp://${next-server}/pxelinux.cfg/macaddress

When I boot my server it gats all the way to the tftp file and just gets stuck no errors it simply outputs -> tftp://10.10.10.10/pxelinux.cfg/macaddress... ok

and hangs.

If I change the protocol from tftp tp http it works.

I know tftp works on my network as other OS types are working fine. There is no firewall as this is a lab environment. I have http, https and tftp enabled in my general.h file. I have read through mang of the tftp threads on this forum and nothing seems to apply.

Not sure how to troubleshoot further

UPDATE:

I enabled logging using this
#define LOG_LEVEL LOG_ALL
#define CONSOLE_PCBIOS CONSOLE_USAGE_ALL

When I boot, I can now see that it downloads the pxe config file (mac address file ) and the when it execute it stops. My config file just contains

#!ipxe
echo HELLO
chain http://servername/ipxescript

Hi,

I am working on HP servers with a custom ipxe.efirom. I am observing that during the boot process my option rom get loaded but when its just about to boot the system sometime hangs while enumerating the boot devices.
This is being observed in both legacy and uefi boot modes. I am currently working in legacy mode. This is also happening intermittently so some time it works and some it fails. When it does work my remove function gets called, but when the system hangs i dont see any removes.
I want to know if someone can point out what process calls the driver_remove for me please.

slow ipxe menu

Hi all,

I have a couple of POS computers that have a slow text output when ipxe is loaded after the dhcp request.
When searching on the web i found a post that someone compiled serial console into ipxe that was causing the issue.
I've tried compiling ipxe without serial_console but the issue persists.

Many other POS computers with serial interfaces do work normal so im thinking this is an hardware issue but im not sure.
Do any of you experience the same issue?

Also i've tried to play with the baudrate when compiling with serial_console and text output gets even slower.
Anyone has a brilliant idea?
Thanks!

Best regards,

IPXE LLDP and type casting

Hi Guys,
I have made sosme changes to support LLDP protocol in ipxe.

The code itself working as expected. But I can not make ipxe to set ip-address on interface. There is a mess with a type.
