[RESOLVED] cd-rom not recognized by bios

[koldo]

How can I put a cd-rom reader into a old 486 with a Phoenix bios 4.03. It cannot detect that the device is connected to IDE2. Bios setting to IDE2 is 'NONE'. The cable is properly installed and the CD unit works OK in other PC.
The system has in IDE1 a secondary drive configured with EZ-Drive.

Verify your CD-ROM is set as Master, if it's a stand-alone device on Secondary IDE.
Then switch to Auto under BIOS, so it can be autodetected.
It should normally work.
If not, try connecting it as a Slave on the Primary IDE cable.

The drive is set as 'MASTER' and the Bios 'AUTO' option is not present.

I'm sure you've checked this but just in case, make sure the secondary controller isn't disabled in BIOS. In the old days we used to disable this to save the IRQ. Of course, if this is an older 486 the controller is an add-on card and you would have to know what jumpers to check...

[koldo]

the jumper of the secondary IDE is active. ¿?

Install the Mitsumi cdrom driver on the system
It will scan the IDE channels and if there is a cdrom it will detect it and install it

I think the file name for the driver is ide-158.exe

It acts as a generic driver and it works for almost every IDE cdrom ive tried

Make sure there is no cable select jumper in place on the back of the drive. This will cause the type of problem you describe.

The device is attached as 'SLAVE' in IDE1 an works fine. The second disk (as Master) in IDE2 don`t work but in not important.
