Some CD drives have proprietary drivers but since it worked to install windows, we have a good clue to work with. Check and see if under device manager the IDE channels are working, this means not marked with a yellow exclamation mark. If one or any are, the protected mode drivers are locked. Open regedit and go to this key. HKEY_LOCAL_MACHINE > SYSTEM > CURRENTCONTROLSET > SERVICES > VXD > IOS Click on the NOIDE entry on the right side of the regedit program and hit delete. Close regedit and reboot, this will reset the protected mode drivers. If this doesn't do it, try changing from DMA transfer protocol to P10. It is on the settings page of the CD rom once you get it into device manager. If it's still not working, you may have use DOS mode drivers and that's to complicated to describe here.

When you install Microsoft Windows XP, you may receive the following error message:
[Files Needed]
The file 'Asms' on Windows XP Professional CD-ROM is needed. Type the path where the file is located, and then click OK.
This issue may occur if the Setup program cannot communicate with the CD-ROM drive.
To resolve this issue, use the appropriate method for your computer.
Hard disk formatted with FAT or FAT32 file system
If the hard disk is formatted with the FAT file system or with the FAT32 file system, follow these steps:
Use a Microsoft Windows 98 Second Edition or Microsoft Windows Millennium Edition (Me) Startup disk with CD-ROM drivers to restart the computer.
Copy the Xcopy.exe tool from the Windows 98 Second Edition CD-ROM, the Windows Millennium Edition (Me) CD-ROM, or the hard disk to the Windows Startup disk. To do this, use the appropriate method.
Windows 98 Second Edition CD-ROM
Insert the Windows 98 Second Edition CD-ROM in the CD-ROM or DVD-ROM drive, and then at the command prompt type the following lines, pressing ENTER after you type each line, where cd-rom is the drive letter of the CD-ROM or DVD-ROM drive:
copy cd-rom:\win98\smartdrv.exe
copy cd-rom:\tools\oldmsdos\xcopy*.*
Windows Millennium Edition (Me) CD-ROM
Insert the Windows Millennium Edition (Me) CD-ROM in the CD-ROM or DVD-ROM drive, at the command prompt type the following lines where cd-rom is the drive letter of the CD-ROM or DVD-ROM drive, and then press ENTER after you type each line:
copy cd-rom:\win9x\smartdrv.exe
extract cd-rom:\win9x\ xcopy.exe /L c:\ xcopy.exe
extract cd-rom:\win9x\ xcopy32.exe /L c:\ xcopy32.exe
extract cd-rom:\win9x\ xcopy32.mod /L c:\ xcopy32.mod
Hard disk
At the command prompt, type the following lines where drive is the drive letter of the hard disk where Windows is installed, and then press ENTER after you type each line:
copy drive:\windows\smartdrv.*
copy drive:\windows\xcopy*.*
Eject the Windows 98 or Windows Millennium Edition (Me) CD-ROM, and then insert the Windows XP Professional CD-ROM.
Copy the I386 folder and all its subfolders to the hard disk. To do this, type the following lines at the command prompt where cd-rom is the drive letter of the CD-ROM drive, and drive is the drive letter of the hard disk, and then press ENTER after you type each line:
xcopy cd-rom:\i386 drive:\i386 /e
Restart the computer, and then start the Setup program again.
When you receive the error message, click Browse, and then type the path of the I386 folder on the hard disk.
Note You may be prompted several times for the location of this folder. If Browse is not available, see the "Hard disk formatted with NTFS file system" section.
Hard disk formatted with NTFS file system
If the hard disk is formatted with the NTFS file system and you are upgrading an earlier version of Windows, use one of the following methods.
Method 1
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 ( ) How to back up and restore the registry in Windows
When you receive the error message, press SHIFT+F10 to start a command session.
Type regedit.exe, and then press ENTER.
On the File menu, click Load Hive, and then load %Windir%\System32\Config\System.sav.
When you are prompted to specify a name, type Test.
Locate and then click the following key:
Delete the UPPERFILTERS and LOWERFILTERS registry keys.
Repeat steps 6 and 7 for the other ControlSet# keys under the Test hive.
Click File, and then click Exit to quit Registry Editor.
If the path in the error message is the correct drive letter for the CD-ROM drive, click OK to continue the Setup program.
If you receive the error message again, the Setup program cannot correctly read from the CD-ROM drive, or the path information is incorrect. In this case, restart your computer and let the Setup program resume.
Method 2
If you cannot start Regedit.exe at the command prompt, and there is another available partition where you can install Windows on the hard disk, follow these steps:
Install Windows in the other partition.
Start the new installation of Windows, and then start Regedit.exe.
Follow the steps in method 1, but load the System.sav hive from the original Windows folder.
Method 3
If you are not using a retail Windows XP CD-ROM with a hologram (for example, if you are using a burned CD-ROM), try to run the Setup program from a retail CD-ROM with a hologram. To verify this, start the computer by using Recovery Console, and then check the C:\$win_nt$.~ls folder. Look for the Asms folder. If the folder is missing or the files that it contains are zero bytes, the CD-ROM was not burned correctly.
For additional information about how to use Recovery Console, click the following article number to view the article in the Microsoft Knowledge Base:

Problem when downloading file says installer integrity check has failed. common causes include incomplete download and damaged media. cannot install files.

If you're reading the file from a CD-ROM, then either:
* the CD-ROM drive is reading incorrectly,
* the CD-ROM is scratched, and thus cannot be read 100% correctly,
* bad RAM in your computer, that "corrupts" the data being read from the disk into the RAM.

Replace the CD-ROM.
Replace the CD disk.
Download "MEMTEST86+", and run it, to test the RAM; replace, if necessary.

Cd rom will not read. have just put windows 98 on instead of xp, hard disc was formated, have win 98 now, but cd wont work or if i plug in usb memory stick

With Windows 98 you MUST install a suitable driver in addition to Windows 98 to talk to CD Roms. I believe there is also a general service routine that must be loaded.

XP has all this functionality built in.

When i set cd rom as my first boot device and if i restart my pc its not booting through cd(for win98 installation)

1, Check if your cd-rom is reading properly, You can do that by connecting the cd-rom to another computer
2. Hope it's the first point because if not, than it's not the cd-rom the problem but the main comptroller on the motherboard. If this is the case then the only alternative is replacing the motherboard.
