- Subject: GLINT - 3DEMON FAQ (1/1)
- Date: 3 Feb 1995 18:57:22 GMT
-
- The 3DEMON by Omnicomp is a PCI-bus 3D accelerator, based on the GLINT
- 300SX chip from 3Dlabs. Omnicomp began shipping full-production 3DEMONs in
- the last 2 weeks of January. There have been many questions generated
- about the capabilities of this graphics board. We have answered the most
- common questions below.
-
- If there are other questions you need answered, or feel should be in this
- list, please contact Omnicomp by E-Mail (omnicmp@phoenix.phoenix.net), fax
- (713-827-7540), or phone (713-464-2990).

- Subject: Q1: How much memory does the 3DEMON have?
-
- A: The 3DEMON model SX44 has 4 MB of VRAM for the frame buffer, and 4 MB
- of DRAM for the local buffer (Z-buffer). The 3DEMON model SX48 has 4
- MB of VRAM for the frame buffer and 8 MB of DRAM for the local buffer
- (Z-buffer).
-
- ------
- Subject: Q2: What is the price of the 3DEMON?
-
- A: The list price (Manufacturer's Suggested Retail Price) of the 3DEMON
- model SX44 (4 MB VRAM + 4MB DRAM) is $1,995. The list price of the
- 3DEMON model SX48 (4 MB VRAM + 4MB DRAM) is $2,390. Reseller,
- Developer, and quantity discounts are available.

- Subject: Q3: Does the 3DEMON support Texture Mapping? What about the
- GLiNT 300TX?
-
- A: The 3DEMON with the GLiNT 300SX DOES support texture mapping. The
- 300SX does the filtering and application calculations for texture
- mapping. The host provides the data, including the texture, to the
- 300SX. The 300TX, when available, will allow storage of textures in
- the local buffer. This is one reason the 3DEMON is designed to
- support an 8 MB local buffer. Boards purchased with the 300SX are not
- upgradeable to change to the 300TX because the GLiNT is a 304 pin,
- fine pitch, surface mount device. There has been some mis-
- understanding that the 300SX does not support texture mapping. This
- is because the BETA version of the OpenGL drivers for Windows NT do
- not currently implement texture mapping. This was a software
- limitation, and not a hardware limitation.

- Subject: Q4: Should I wait a few months before buying a 3DEMON, when the
- hardware is more stable?
-
- A: Today's shipping 3DEMON has very stable hardware. It has already been
- a few months since the first board using the GLINT was built. By now,
- the hardware bugs have been worked out, and all modifications or
- changes are in the shipping version of the 3DEMON. In fact, the
- 3DEMON has NO wires or last-minute modifications on the board.
- Drivers today are at the final stages of BETA. Updated release
- versions of the drivers will be available near the end of February.
- Current drivers should support any existing application written to
- OpenGL under Windows NT.

- Subject: Q5: What motherboards are compatible with the 3DEMON?
-
- A: Omnicomp has tested the 3DEMON with the INTEL designed PENTIUM
- motherboard used by Gateway and DELL in their PENTIUM 90 machines. We
- have also tested it with various motherboards using the OPTI chipset
- for PENTIUM. The 3DEMON has also been tested in MIPS-based Windows NT
- systems. The board is now in the hands of many customers, and we are
- keeping track of the systems our customers are using.
-
- ------
- Subject: Q6: What system configuration is recommended for the 3DEMON?
-
- A: For INTEL-based Windows NT, we recommend a PENTIUM-90 with 32 MB RAM
- for OpenGL development.
-
- ------
- Subject: Q7: Does the 3DEMON support PCI bus-mastering?
-
- A: Yes. The 3DEMON conforms to the PCI Local Bus Specification Revision
- 2.0 and does support bus-mastering.
-
- ------
- Subject: Q8: Does the 3DEMON have on-board VGA?
-
- A: The 3DEMON does not support VGA BIOS calls. For an INTEL based
- system, you must have a VGA card installed for system boot, or DOS
- command-line. Single monitor operation is provided using an external
- pass-thru. This form of pass-thru is compatible with any VGA. Once
- in Windows, the 3DEMON provides the whole display. In other platforms
- such as MIPS, the 3DEMON may often act as a boot display. This varies
- by system vendor.
-

- Subject: Q9: When will I see a $600 GLiNT board?
-
- A: A $600 GLiNT design would be possible using 2 MB of DRAM (not VRAM)
- for the frame buffer, and 2 MB or less of DRAM for the local buffer.
- Also, such a price would require production volume in the tens of
- thousands, or possibly a lower-end version of the chip, if 3Dlabs
- chooses to do so. Such a board would be targeted at the home games
- market. This type of board would not meet the performance of a 4 MB
- VRAM + 4 MB DRAM 300SX design.
