I have a Win98 computer and have a custom DOS configuration used for networking to a DOS laptop. Now, the Win98 computer's internal CD-ROM

that? I have the necessary DOS-mode USB drivers.
You can't disable a single IDE drive (CD-ROM or HDD) in Windows 9x. So,
there is no solution. Only workarounds.
1. For CD-ROMs, remove its drive letter via its device properties dialog in Device Manager.
2. Disable IDE controller's primary/secondary channel from the Device
Manager. Note: this will disable any attached master & slave devices for
that channel.
3. Disable IDE controller's primary/secondary channel from the BIOS. Note:
this will disable any attached master & slave devices for that channel. Or
if BIOS supports disabling a specific IDE channel's master or slave device,
use that instead.
4. Unplug both the power and data cable to the storage device.
Note: workaround #1 and #2 should not be used if storage device detection is causing unacceptable delay or even freeze the system.
