Solve : CD ROM NOT RECOGNIZED IN BIOS? |
|
Answer» I'm trying to install Windows on a computer I just received but the bios isn't recognizing the CD ROM drive so I can't install windows via CD. I've tried several different cable configurations and a couple of different CD ROM drives. it has power just not showing up in the bios as present. The hard disk format (i.e., loader) *can* affect the video when using a BartPE boot disc [a CDROM], especially with a digital video cable. Wow! THREAD "Blank Video With Dell Optiplex Gx280" http://www.911cd.net/forums//index.php?showtopic=11310&mode=threaded The Boot Order does have the CD first but the bios says no CDROM is present in the system. As far as the cable I'm just using standard cabeling that probably came with the system. I'm thinking of buying a USB CDROM drive for cheap tomorrow and test that out to see if it can detect that. Any other ideas?0. USB Drive. Not sure yet what your system supports. Also don't have experience booting from USB Drive, so recommend continuing to work on getting system BIOS to recognize a CD-ROM device (using whatever interface your system supports: IDE, SCSI, USB). 1. Which system case does your system use (see system case link just given): o Small Form-Factor Computer o Small Desktop Computer o Desktop Computer o Small Mini-Tower Computer o Mini-Tower Computer 2. What "exactly" does the BIOS report for your IDE, SATA, USB devices (Hard Drives, CD-ROM)? Quote I'm just using standard cabeling that probably came with the system. Are the pins in the connectors like this? or like this? The connectors are the second type. As far as the form factor, its just a standard town and tne bios reports not present next to the cc rom and the other sata drives that are obvioujsly not there since there is only one.

Tower. For now I'm going to assume you have the "Mini-Tower Computer"... Or the "Desktop Computer"... Or the ... You know how it goes. 2. BIOS Drive Detection. So you have a single SATA hard drive and a single CD-ROM drive installed in the tower. Is there an internal floppy drive? Does BIOS report them by drive number; e.g. 0, 1, 2, 4; or by interface; e.g. IDE Primary Master (PM), IDE Primary Slave (PS)? BIOS reports the CD-ROM not present. What is the "exact" message? Does BIOS see the single SATA hard drive? What is the "exact" message? BIOS reports the other SATA drives not present??? What are the "exact" messages? 3. CD-ROM Drive. You've tried several CD-ROMs with same result. a. Is the CD-ROM drive connected to the only EIDE PORT on the motherboard? b. Is it a ribbon cable with 40 wires or 80 wires? c. Does ribbon cable have one or two connectors for drives? If two, is the CD-ROM connected to the middle connector or the end connector? If two, is anything connected to the other connection? What? d. Are the jumpers on the CD-ROM drive set to "Master", "Slave", "Single", or "Cable Select"? e. With power off: Have you tried reseating the ribbon cable at both ends? Have you tried reseating the drive's power connector - (or using a different one)? f. Have you tried another known working EIDE cable? 40 or 80 wire cable? g. Have you ensured the EIDE port is "enabled" using CMOS setup for system BIOS? Is the IDE controller enabled in system BIOS? You'd have to be pretty unlucky to have a "dead" IDE/EIDE controller or port. 4. Hard Drive. The SATA hard drive is connected to the SATA 0 port on the motherboard? 5. System Setup. Use System Setup to disable devices and ports you won't be using to free up system resources (IRQs, IO Addresses), e.g. Serial, Parallel, SATA 2 ports. 6. Dell Diagnostics. If you use the F12 FUNCTION key during system startup, can you access the Dell diagnostics on the hard drive? What is the light pattern on the Dell diagnostic LEDs? 7. Floppy Drive. If you have access to a bootable floppy drive, find out what works on that computer? You should be able to download and create bootable floppies to test the system RAM and hard drive. |
