Motherboard Information
Processor
The processor can be upgraded to 133MHz Pentium Processor. Ensure Board speed is set correctly via jumpers JP7, JP8, and J4.
| Clock Speed | JP7 | JP8 | J4 |
| 75MHz | Off | Off | Off |
| 90MHz | On | Off | Off |
| 100MHz | On | On | Off |
| 120MHz | On | Off | On |
| 133MHz | On | On | On |
Memory
8MB (2 x 4MB Fast Page RAM in Banks 3&4) supplied with machine. To upgrade memory on this machine you must insert 72 pin PARITY SIMMs IN EQUAL SIZE PAIRS into spare 72 pin SIMM sockets. The chips must have an access time of 70 nanoseconds or less and must have lead connectors (gold is not acceptable due to corrosion) and be PARITY type.
RAM can be upgraded to 64MB using 1MB, 2MB, 4MB, 8MB, and 16MB Fast Page Mode SIMMS only, in identical pairs, in either Bank0 (SIMM 3&4) or Bank 1 (SIMM 1&2). Each bank is 2 SIMM sockets. The manual refers to "double density" SIMM's this is interpreted as follows: An 8MB double density SIMM is actually a 16MB SIMM.
L2 Cache
Upgradeable to 512 KB only.

Known Issues
CD-ROM Drive Problems
These computers have been shipped from the manufactures with incorrect settings and need modifying. On initial start-up through Windows 95, the machine moves slowly through the start-up files, sometimes finding the CD ROM and some times not. While the CD-ROM icon is visible no files are actually visible with a CD inserted, and the CD Rom system does not work Solution -
The CD Rom was connected to the motherboard and set-up as a slave at the rear of the CD Rom. This was easily corrected by removing the jumper and resetting it to the master position. (If the CD Rom was connected to the sound card and configured as a slave this is correct!).
The MS-DOS Drivers for the CD-ROM are normally in a directory called C:\ECS. There should be three files,
- CDPLAY.EXE which is a DOS music CD player
- ECSCDIDE.SYS which is the CD driver
- MSCDEX.EXE
Insert this line in Config.sys: DeviceHigh=C:\ECS\ECSCDIDE.SYS /D:MSCD000
Insert this line in Autoexec.bat: LH C:\ESC\MSCDEX.EXE /D: MSCD000
Graphics
Number 9 vision 330 video card gives simplified graphics, ie isn't reaching required resolution. The solution is to download and install the latest drivers.
