Calcula el tiempo estimado restante usando velocidad promedio desde el inicio de la descarga (más estable que velocidad instantánea para ETA). Formato mm:ss para descargas < 1 hora, h:mm:ss para descargas largas. Muestra "--:--" mientras no hay datos suficientes para estimar. ETA solo aparece cuando el servidor informa Content-Length.

# directamente desde el menú GRUB, sin necesidad de pendrive.
|
|
# Las ISOs se pueden descargar desde el catálogo (isos.conf) o
|
|
# agregarse desde un archivo local.
