i have an advent 7302 laptop with windows vista installed, im not sure what i done but i think i may have tampered with the phoenix bios unitlity which is version d3b11. when i turn on my laptop the advent logo comes up but then the screen just goes black with a flashing underscore in the top left had corner and when i try to press any key i hear this beeping sound and nothing happens it remains blank and if i press ctrl alt del the lap top just re starts and the same black screen with the flashing under scores reapears . i did go to the boot section ofthe bios unitity and rearanged the drivers but then instead of the flashing coser i recived a black screan saying "for realtek RTL8139(x)/8130/810 PCI fast ethernet controller v2.13 (020326)
PXE-E61 : media test failure,check cable
