|If you have or can borrow a CD for a newer operating system - e.g. Win 98, 98SE, or Win ME - and have a Product Key for the CD, we recommend that you DO NOT install Win 95. It is inferior to later operating systems and very poorly supported these days. If it isn't Win 95 version OSR2 or later, you can't use USB anything with it (OSR2 or "With USB support" is printed on the CD if it supports USB). |
What model is the CD drive ?
What model is the Compaq computer ?
That should be on a label on the outside of the case somewhere.
Is it an Win 95 Upgrade CD, or a Full installation CD?
If it's an Upgrade CD, you must have proof you have a previous qualifying operating system - e.g. you must at least have the installation floppy disk set available for Setup to find certain files.
Since you're trying to install Win 95, the computer may be really old, and the CD drive may be an ancient proprietary one that must be connected to the header on a proprietary drive controller card, or to a proprietary wired header on a sound card.
If that header is 40 pin, if you connect both the proprietary CD drive and a regular IDE hard drive to the same data cable on that proprietary header , neither drive will work, and neither drive will spin. If you disconnect the IDE drive from the data cable it will spin fine,
and the CD drive will spin fine, and work fine, if the drivers have been loaded for it.
If you have an old system, the Boot Order or similar in older bios versions has to be set in the bios Setup to boot from a CD drive first in order to boot from a bootable disk - you can only boot from either a hard drive or a CD drive E.g. the Aug 1999 mboard on the 98SE system I have has the Award 4.51PG bios and it's that way.
That's probably not relevant anyway.
As DAVEINCAPS has said, I don't believe the WIN 95 CDs are bootable in any case.
The Win 95 CDs have no built in ability to recognize a CD drive. You must boot the computer from an operating system floppy disk (e.g. has MSDos 6.2 system files) that has the drivers for the CD drive on the floppy, MSCDEX.exe must be on the floppy, and properly configured lines must be in Autoexec.bat and Config.sys on the floppy for the drivers and for mscdex.exe to make the CD drive work in "real" mode.
If you have a proprietary CD drive, you must boot the computer from a floppy disk that has the proprietary drivers on the floppy and the proper line configuration in Autoexec.bat and Config.sys .
If you have an IDE CD drive, you must either have the cd drive drivers for the model, or generic IDE cd drive drivers, on the floppy, and the proper line configuration in Autoexec.bat and Config.sys
Once Win 95's Setup has finished,
- if the CD drive is IDE, you don't need to load the drivers for it in "real" mode anymore.
- if the CD drive is proprietary, you must use Add Hardware to select it's type, then once the built in drivers for that have been installed, you don't need to load the drivers for it in "real" mode anymore.
You can delete or disable the lines that load the "real" mode drivers in Autoexec.bat and Config.sys in Windows itself (you still need them in Autoexec.bat and Config.sys when you boot the computer from a floppy disk, if you want to be able to use the CD drive.)
E.g. Panasionic (Matsushita) proprietary CD drives use a 40 pin data header, and a proprietary drive controller data connection, and once Win 95's Setup has finished, you can use Add New Hardware to manually install the built in drivers Win 95 has for it.
