Bios does not detect my external DVDwriter

[mj2000]

Hello !

I use Transcend external DVDwriter Modell TS8X DVDR-K on Dell Inspiron 1520

In Windows, there is no problem and i use it easily, but the bios does not recognize it and i can t boot any cd from it.

Please help and please such as other forums, do not explain the configuration of bios to boot from cd instead of internal hard drive !

I am saying that bios does not detect my external hard drive, but only my original dvd- rom.

And as i said, windows detects it easily , but not Bios !

Please help ! Thanks a lot !

USB ports deliver both data and power, and some external usb drives get additional power from a separate AC power cord, but I think your DVD does not have a separate cord. Flash drives consume almost no power but a spinning device like a DVD needs a lot of power, so its possible that your drive is not getting enough power until windows loads the USB driver. There should be a place in cmos/bios setup where you can define hard drives and usb devices, but I can't find the 1520 bios screens online to guide you.

so please tell me what the option is or looks like, that i have to look for in bios.

I didn t find an option related to what you mentioned.

That statement sounds like you are looking at the boot menu, which you access by hitting F10 or F12 or whatever (not sure for your computer), as opposed to the bios, which is a series of detailed screens, and is usually accessed by F1 or DEL. On my system, when in bios and on the "boot order" screen, there are selections for USB, USB-FDD, and USB-CD. I'd try them all. Bios/setups vary a lot from computer to computer though. Without a link to the bios screen detail for your machine, I'm in the dark.
