Disk Drives Over 1 Gigabyte Questions and Answers About Extended Translation What happens if I enable extended translation with SCSI drives that are less than 1 GByte in capacity? Drives handled by the BIOS will use extended translation provided they are over 1 GByte in formatted capacity. Drives with less than 1 GByte of formatted capacity will use standard translation regardless of whether extended translation is enabled. What if I have more than two fixed disk drives on the host adapter? You can use up to seven fixed disk drives under the BIOS provided you are running DOS 5.0. What if I use older versions of software drivers when extended translation is enabled? To protect your data, the host adapter will lock out any driver that does not identify itself as capable of extended translation. If you need to use software that is not compatible with extended translation, do not enable extended translation. Ì Adaptec AHA-2740 Series User's Manual Stock Number: 510381-00 / Rev.
