- 1.0.0 Installation Notes
- ------------------------
-
- 1.1.0 Installing Over Existing UltraSound Software
- --------------------------------------------------
- If you experience problems after installing this new set of software,
- simply delete your UltraSound directory and re-install.
-
- 1.1.1 Users with 16-Bit Recording Option (Daughter Board)
- ---------------------------------------------------------
- The install will not auto-detect the presence of a 16-bit recording
- board. To configure the 16-bit recording card for Windows, double click
- on the UltraSound Configuration icon in the Gravis Program Group in
- Windows. Under "card type," select "16-bit recording card." If you do
- not do this, you may not hear anything under Windows.
-
- 1.1.2 Important Note on Choosing the Base Address
- -------------------------------------------------
- If your CD-ROM drive uses address 3x0 Hex, DO NOT choose 2x0 Hex for
- your UltraSound base address, or your computer may crash. 'X' denotes a
- port address. (For example, if your CD-ROM address is 320 Hex, do not
- choose 220Hex for your UltraSound base address.)
-
- 1.1.3 Temporary Directories
- ---------------------------
- After installation a temporary directory, ADMALTOI or ISFYZQVO.TWJ,
- may be left undeleted on some systems. These directories can be safely deleted.
-
- 2.0.0 Setting up for Windows
- ----------------------------
- The UltraSound uses buffers to store sound information when playing and
- recording digital data. The size of these buffers can affect the
- performance of the UltraSound in certain applications. The buffer size
- can be changed in Windows by choosing the UltraSound Configuration icon
- for the Gravis program group under Windows. You can then type in a new
- value for "buf size" in the sections for DMA Channel A and DMA Channel
- B. The default buffer size of 4096 bytes generally gives the best
- results when recording and playing back data. The largest buffer size
- is 8192 bytes. Applications such as voice recognition can work better
- with a smaller buffer. If such an application is not working as
- expected, try using a smaller buffer size. The minimum size is 512.
-
-
- 3.0.0 Memory upgrades
- ---------------------
- The following is a list of DRAM suitable for upgrading your UltraSound:
-
- OKI #MSM514260A-70JS
- NEC #uPD42S4260LE-70 (NOTE 2)
- NEC #uPD424260LE-70 (NOTE 2)
- NEC #uPD424260LE-60R (NOTE 3)
- NEC #uPD42S4260LE-60R (NOTE 3)
- TI #TM545160DZ-80
-
- Note 1: Memory upgrade kits are available from Gravis.
- Note 2: The DRAM indicated above are 60nsec. thru 70nsec. parts. If
- available, the 80nsec. DRAM may also be used.
- Note 3: The "60R" part signifies that the part does not quite meet the
- 60nsec. spec. Basically, it may be considered as a "faster than
- 70nsec. but not quite 60nsec." part.
