1  Informática / Hardware / Es posible mostrar la BIOS por hdmi en un portátil? en: 9 Noviembre 2020, 02:21 am
Hola chicos, estoy intentando convertir un laptop viejo y roto en un servidor, pero estoy topando en eso, mostrar la BIOS por hdmi o vga. Llegué a esta parte (pag 83).

Específicamente en Primary IGFX Boot Display, no se que opción debería marcar, intente todas pero, sigue saliendo el vídeo por la salida lcd. También intente desactivar los gráficos intel pero entonces no da vídeo.
El manual es solo ilustrativo de las opciones que me salen a mi, nunca pude obtener el manual de BIOS del fabricante.

También me salen estas opciones.

El laptop en cuestión era un samsung np470r5e, y le instale una BIOS unlocked porque la oem no traía habilitada las opciones. Pero acá quede colgada porque no son las salidas que esperaría encontrar de un desktop.

¿Me pueden hechar un cable?

Gracias

3  Programación / Programación C/C++ / Problemas make mpfr2.4.2 en: 19 Abril 2018, 19:17 pm
Hola, intento compilar, la librería mpfr para un tutorial en el que se hace compilación cruzada para arm, pero cuando hago make me arroja errores que de momento no soy capas de solucionar, espero me puedan guiar para solucionar el error.

Estoy probando en Manjaro 17.1.8

Los comandos para instalar mpfr que dice el tutorial son los siguientes:

Código
  1. tar jxf mpfr-2.4.2.tar.bz
  2. ./configure -prefix=/usr
  3. make
  4.  
  5. su
  6. make install
  7. exit
  8.  

Obviando las cosas de bash, el problema me viene con make, el primer log es de la configuración:

4  Programación / Bases de Datos / ¿Alguien ha descargado la documentación de MariaDB? en: 25 Mayo 2017, 02:27 am
Hola a todos, me ronda la duda, entre tanto abusar de mi conexión para acudir a la doc de mariadb, me gustaría descargarla, el problema es que busco y busco y solo están los paquetes de instalación, pero nada de la doc que tienen online como lo hace php.

¿Alguien sabe si es posible descargarla de forma oficial?

Hola de nuevo, estaba mirando el subforo desarrollo web y me surgió la intriga, no estaría nada de mal tener un subforo de NodeJs o javascript, ya que  este esta ahora en el back junto a PHP, no se si lo han planteado ya.

Hola que tal, no le he querido preguntar a Google porque nunca he llegado a buen término con esta duda.


Sería posible tomar el disco duro de mi equipo, y copiarlo para correrlo desde virtualbox o algún programa de virtualización en otro equipo?

Saludos y gracias
7  Programación / Bases de Datos / split string[ORACLE 11G] en: 6 Septiembre 2016, 16:19 pm
Hola, espero me puedan dar un indicio de como podría resolver lo siguiente:

Tengo un tabla a, la cual tiene un campo que puede tener n cadenas unidas por el carácter -, ejemplo

Código:
table a
- columnB

select * from a

result:

+columnB+
 cadena1-cadena2


Lo que no se como se podría hacer solo en SQL, sin usar PL/SQL es pasar cada cadena a filas, para que quede de la siguiente forma, pero sin saber cuantas cadenas podrían existir dentro de la columna.


Código:
+columnB+
 cadena1
 cadena2

Espero sus comentarios.

Saludos y gracias

Hola, se que no es tan complejo, pero quiero comprobar que estoy bien.

Como puedo pasar de (-2)^(2/3) a sqrt(-2, 18) (raíz 18 de -2).
