| Catalog subcategory | CD-ROM readers |
|---|---|
| Exact product identifier | AOpen CD-940E |
| Read speed | 40× maximum CD-ROM read; maximum rating is not a guarantee for a particular disc or transfer path. |
| Supported CD formats | CD-ROM Mode 1/2, CD-DA, CD-ROM XA, CD-I and Photo CD; read-only, not a CD-R/RW writer. |
| Host interface | Enhanced IDE / ATAPI (PATA), 40-pin |
| Host and mechanical compatibility | Internal half-height 5.25-inch motorized tray-loading unit. Requires an IDE/ATAPI host, suitable legacy BIOS/OS support and 5 V/12 V power; not slimline or native SATA. |
| Firmware / jumper caveat | Select MA/SL/CS only from the CD-940E manual and the chassis label; the manual’s default may differ by production run. Do not use a generic jumper pin order. Confirm CD-940E versus CD-940E/AKU suffix and board revision before firmware service; do not flash a nearby AOpen CD-40X family image unless it explicitly lists this unit. |
Installation and preservation notes
- Before connection, compare the unit label, interface connector and jumper markings with the model-specific manual. Do not power an uncertain pinout.
- For this PATA/ATAPI unit, assign one master and one slave per IDE channel, or follow Cable Select requirements on a compatible cable.
- Keep the original firmware identity, host adapter/BIOS, driver version, disc type, read-error log and verified image checksum together during preservation work.
- Use this record for read compatibility only: a CD-ROM reader is not evidence of disc-writing support.
