Boot can not detect my cd/dvd - rom

hi

well,after i boot up my system with a bootable cd , in the ms-dos & "boot with support cd-rom" , it say can not detect CD-Drive .

everything is ok after bootup to ms-dos , NTFS Supporting,all drives are availible,it can also Fdisk H.d.d , but can not detect my cd or Dvd-writer . i tested both device in another system & it could detect both of them . but in this ssytem it can't .

mobo:Giga-p35-ds3l
Bios:updated to last version ( still can't detect)
H.D.D:500 MAXTOR/32mb with 6 partition

* both devices are detected & work properly in windows ( xp & vista )
* i tried many bootable cd s & doesn't work
* both device are connected with P-ATA cable but h.d.d is S-ATA

tnx

 

The first thing I would do is to check the jumper settings on the drives. I suggest using one set as Master, the other Slave. You can try reversing those or just connecting one drive at a time.

If it was the old days, I might suspect that the boot disks didn't have the correct drivers available to run the drives, but today that should not be the case.

Have you tried making a bootable CD and booting to that? [You must be booting to a floppy disk.] You may need to check that the CD/DVD is set to boot before the HDD in the BIOS/Startup settings.

Some boot disks I might suggest that are widely compatible are www.bootdisk.com and the diagnostic utility for the HDD.

tnx dear mathman

tnx dear matyhman,but actually i haven't 2 device on my P-ATA Cable, i just tested my cd-rw after that i found my DVD-RW unreadable in MS-DOS Boot . both of device are set to master & tested separately on cable .

well,actually i have no F.D.D On my new system,i just though by myself the timeliofe of F.D.D has come to end . but i created some bootable CD with (Nero,Memtest86+) . all bootable cd are ok with these devices in my another system .

& yes,in bios startup "cd-rom" is the first boot-device before H.D.D .
but there is something interesting,when i want install winVista , in cmd console during installation it'll detect my cd drive !


tnx

 

You have booted to a boot CD, so I expect it must(?) recognise it's own drive. MS-DOS loads as a "virtual" drive in the memory (RAM), so one of the drives you will find is a non-physical (virtual) drive.

Does the bootable disk use MS-DOS from a Windows 98 Startup disk? If so, the virtual drive takes the drive letter of the CD/DVD drive and the CD/DVD drive is pushed to the next drive letter. For example, if the drive letter of the CD/DVD is E: in Windows, when you boot to a Win 98 startup disk, the virtual/RAM drive will be E: and the CD/DVD drive will be F:.

You don't need two optical drives to run the DOS programs. After booting into DOS, you can take the disk out of the drive and replace it with another. You then change directories to the optical drive and run the program.

Make a bootable disk from the www.bootdisk.com website. Since the disks "work" on another computer (can you run Memtest, etc?) it may be the IDE controller that is the problem. If the motherboard has an nVidia chipset, they are problematic with regards IDE/PATA.

yes,it use windows 98 startup disk , but i tried many bootable cd & it cann't detect my CD/DVD & say "no 'mscd001" driver found,abort installation" [ something like this]
i even tested all availible letters in keyboard for my cd/dvd drive .

the major problem is programs like memtest86 use his own boot & IMG file . when i boot with memtest86 bootable cd it can isntall all of my drive & even a virtual drive,but can't detect my cd/dvd .

ok,i try a bootable disk with the url & report details.my P-ATA cable is orginal with mobo,but i try with another cable to see result . my mobo use intel chipset .


very tanx dear mathman

 

Boot can not detect CD-rom drives

Did you ever find out what was wrong? I just got the same MB/intel and mine does the same thing. Tried windows 95, 98, ME booting from floppy but could not detect cd drives. Tried Maxtor and Seagate CD disks and when booting they could not find cd drives. When installing XP it does work from cd drive but seems very slow.

Joe, is it a Maxtor or Seagate drive...or another brand? The model number of the drive should be listed in Device Manager, but I never take "devices" on their face value.

I would like to work on this problem, but I do not have that motherboard . I suggest going to the Intel support website and finding their e-mail contact. Ask there. They may have an "update" or different way of installation.

Matt
PS "Ask there "...Intel would probably like feedback for their products.

I have a different drive but my point is, that the cd disk would not boot, not from xp but from startup, said no cd drive detected, like your problem. Our mother boards are close, yours is the p35 and mine is the ep35, same problem. Did you figure out how to get anything to boot, like into dos and detect the cd drives? I also have Ghost, a disk image program that I boot from floppy. It did work and detect the cd drive but it took twice as long to load, ran at 120mb minute where on other computer over twice that speed. Something is wrong. Will try to contact Gigabyte and ask questions, did you try them?
Joe

 

Sorry, I should have re-read the information. It is an Intel based Gigabyte motherboard. I sent Gigabyte a question (a long time ago) and got no reply. I only use the knowledgebase and FAQs at Gigabyte.

If the problem is speed, check the cables. Pull out the cable connectors at both ends and reseat them. Is it possible you are using an old 40 lead IDE cable instead of an 80 lead cable?

You can put the model number of the CD/DVD drive into a websearch (or look it up at the manufacturer's website) and find the manual/User Guide. Like I said, if the drive is jumpered as CS (Cable Select), try setting it as Master/Slave. It will be explained in the User Guide.
