systemrescuecd 5.1.2 not boot correctly from LAN

[tadziuuu]

Hello everyone,

I’ve tried all the possibilities on this forum and other sources, but I failed…

FOG Project=v1.5.10
OS Ubuntu 23.04 [on Proxmox 8.0.4]
DHCP on own router + DNSMAQ

boot from PXE works fine,
I have a problem with System Rescue CD 5.1.2

my configuration based on the following:
https://forums.fogproject.org/topic/12263/booting-system-rescue-cd-5-2-2?_=1692208738697

Parameters_option_1
kernel tftp://${fog-ip}/os/RescueCd/5.1.2/rescue64 docache setkmap=us
initrd tftp://${fog-ip}/os/RescueCd/5.1.2/initram.igz
imgargs rescue64 initrd=initram.igz netboot=http://${fog-ip}/images/os/RescueCd/5.1.2/sysrcd.dat setkmap=us docache
boot || goto MENU

Parameters_option_2
kernel tftp://${fog-ip}/os/RescueCd/5.1.2/rescue64 scandelay=1 docache setkmap=us netboot=http://${fog-ip}/images/os/RescueCd/5.1.2/sysrcd.dat
initrd tftp://${fog-ip}/os/RescueCd/5.1.2/initram.igz
boot || goto MENU

both are not working properly for me

the only thing noticed is that
sysrcd.dat is about 447MB and in the screenshot you can see that it only downloads 321MB

please help, where could be the error?

thank you in advance for your help!

greetings Tadziuuu

sorry for the confusion,

its works!

there was not enough RAM!
the question is how to do it for older devices to emulate reading from a CD …
is it possible?

greetings Tadziuuu

@tadziuuu Are you referring to booting bios based computers? If yes then use memdisk to load the cd iso image into memory. The one caveat here is that the iso disk must be less than 2GB in size since memdisk is a 32 bit application and there needs to be room in ram for the OS to boot from the iso image. In the same tutorial you found the parameters in your first post, search for memdisk to see what parameters you need.
