Symptoms

After installation, CDROM unavailable

Hardware

Toshiba 2150CD series laptop computers (486 DX4-75, built in IDE CDROM, etc)

Toshiba 2150CDS

Problem

After installation, the system couldn't recognize the CDROM.

Procedure

Edit the Config.SYS. Look for the line:

    BASEDEV=IBM2TOS1.SYS /s0=2 /c0=15

Change the /c0=15 to /c0=# where # is a free IRQ (11?).

Notes

The /C0=# appears to be reserving an IRQ for the PCMCIA driver, therefore, this will only affect you if you've installed PCMCIA support. The default IRQ for the driver on my machine was IRQ 15, the second IDE channel (hence the CDROM). Sense the BASEDEV statements load before the CDROM filters (IBMIDE.FLT) the filter couldn't locate the CDROM.

This problem did not occur in OS/2 Warp Connect.

Don't forget to make a backup of your config.sys! I'm not responsible for system damage or data loss
