Hello everyone and best wishes for 2023 :) I have an old *Garmin Drive Smart 50 GPS* and I want to be able to attach it when it is in preboot mode to a VM hosted by a *Debian 11 host*. From what I understand, the preboot mode allows us to flash a firmware before the GPS actually starts (used among other things when the GPS is soft bricked). When I connect the GPS to the host it gives: |root at host:~# journalctl -kf|| ||# GPS in MT...

...a 64bit VM with VMXNET3 and go there this result: [image: cptime.png] (can everybody see the picture?) The download of a 180MB large file (Parted Magic initrd) takes between 60 and 72 seconds, which is about 2.6 to 2.3 MiB/s. Can this go any faster? Or is this the most that we can get out of a preboot environment? BTW, what is the meaning of the +0, +1, -1 lines? Maybe you add there some hint to make it self-explanatory.

so I want to install c6.2 x86_64 onto a 2.7TB /dev/sda ... its a virgin machine with no software, using pxe boot. disk druid or whatever seems to only want to let me have like 2tb of default stuff, I'm guessing because its not using GPT? do I need to preboot into a shell or something and use parted before I can install ? -- john r pierce N 37, W 122 santa cruz ca mid-left coast

Only in internal bootable usb port. That's usually fine because the cdrom can be mounted as loop device. No need for a real cdrom. Regards...

Ok, syslinux is what it is, and I love the way it just works. I looked up linuxBios and found what I was looking for. A project in 2000 called "LOBOS (Linux OS Boots Linux OS): Booting a Kernel in 32-bit Mode? It looks like this would do what I need, but I can't find any working code. I like the Idea of booting a simple fail safe system and restarting a production kernel. Yes,

...tBoot is consisted of GRUB and BuildRoot (BusyBox). It is not simple boot loader. It boots a mini Linux, sets up the network, obtains hypervisor, kernel, and miniroot form a HTTP server, and reboots them with "kexec". The new OS boots with loopback-mounting HTTP-FUSE CLOOP. So InetBoot is PreBoot-Linux which adds some operations before targeted OS. InetBoot can download a script and execute it. This function makes flexible to control the PreBoot-Linux. Xenoppix uses this function. HTTP-FUSE CLOOP saves parts of block device (block files) on a local storage. The saved block files pre...

I see there's a memtest on the Linux discs I've created... would it be possible to put another program in place (a module, perhaps?) that can calculate a hash using a certain algorithm (i.e. SHA512 or similar) to validate and print out the hash of the boot ISO before booting it? The integrity of the ISO is absolutely critical. Thanks, Bret

I saw a section entitled "PXELINUX and the Windows Remote Install Server", but there was nothing below it. I'm trying to figure out how to do this. Any advise would be appreciated. Do you suggest PXE, Etherboot, or Netboot? Could someone explain the difference? I still haven't figured out how all this fits together yet. Thanks.

These cards have a built-in DHCP and TFTP client. You can use pxeboot (by H. Peter Anvin, the same person that wrote isolinux and syslinux), which can be found at http://syslinux.zytor.com.

Hello ! I am completely new to syslinux. I followed this instruction manually: http://www.wonkity.com/~wblock/docs/html/pxe.html I am on debian and do not have syslinux installed, but using this debian box as a tftp server. I had to modify the instructions given by the installation above. I downloaded the 6.02 version and copied the files to the tftp root. I am using dnsmasq as a tftp

Hi, I have a Linux server at ip address 10.215.144.7 running DHCP, TFTP and syslinux.

I have been trying for the past few months to set up my raspberry pi to do incremental backups using time machine over Samba since AFP is being deprecated. Also since the latest release of samba (4.8.0) came out with support for time machine I decided to compile it myself and give it a go. The drive is formatted in HFS plus. The main problem that I am having is that even though I can mount the
