I saw a posting here a while back concerning problems with OPTI chipsets on Pentium 90 Motherboards. I would like to get a semi-technical advise/response on the current problems. I am a 3DS dealer along with generic systems, and need to convience a few others to go with the Intel Neptune. If anyone has some hard facts, please let me know. Thanks, Jim Pope Denver

Jim, >> OPTI chipsets on Pentium 90 Motherboards. Pick up the Sept. 27, 1994 issue of PC Magazine. In their review of forty p90's, they mentioned that the Neptune chipsets outperformed the Opti chipsets by about 10%. I've built a number of 3DS systems based on Intel's Plato motherboard with the Neptune chipset, and they have performed exceptionally well. The bios is flash upgradable, and the onboard PCI controllers and I.O. have given us no problems. (Knock on silicon…) It is important to upgrade to the 1.00.08.AX1 version of the bios if you are planning on using SCSI. John

John; How can you tell what BIOS version is in my Plato Intel MB? And what does the BIOS upgrade change? And last but not least, how can I upgrade by bios version? Zac (AZ-TECH) Berkeley

Zak, >> How can you tell what BIOS version is in my Plato Intel MB? And what does the BIOS upgrade change? And last but not least, how can I upgrade by bios version? If you have a Plato MB, you will see the bios version when you first start up your computer; it should be something like 1.00.03.AX1. There is a complete BIOS revision history in the PLATOHLP.HLP file. There are several changes, starting with 1.00.03. The only thing mentioned as being changed from 1.00.06 to 1.00.08 was, (and I quote): LBX A0 errata fix. Normally seen by SCSI not being able to boot. If you aren't having problems with SCSI booting, it sounds like the update from the previous 1.00.06.AX1 might not be necessary. If you have 1.00.03, it is necessary to go to 1.00.06 before you can go to 1.00.08 or higher. People have apparently found some new bugs in 1.00.10, and many have gone back to 1.00.08. The necessary files are available from the Intel iPAN BBS: 916-356-3600 PLATOUP.EXE (1.00.03 -> 1.00.06) 10008AX1.EXE (1.00.06 -> 1.00.08) PLATOHLP.HLP (A Windows help file that has complete revision history and setup info, including graphics. Very nice!) If you do want to update your bios, be sure to read the documentation carefully. It's necessary to copy the files to a bootable floppy, and start from there; it's really pretty easy. John

Why is this bios upgrade deeded for SCSI? Ian.

RE: Plato bios w/SCSI Thanks! Ian.

there is definatly a problem with the opti chipset and the pentium 90! we have had 2 systems consistently lockup with 3ds and opti. we replaced them with the intel plato/neptune mother boards and are running 10% faster then the opti ones. we are very happy with the intel boards. sherwood animations

Thanks for the information. JP

Sherwood: Which BIOS revision are you running on your Intel 90Mhz boards ?

sherwood, I was wondering what video card you were using on your Intel motherboards. I posted several messages about trying to get an ATI Mach 64 w/4mb to work on an Intel pentium 90. This message is one of the latest. I haven't gotten a lot of response on this problem. Maybe I haven't been checking the forum often enough. Since this message I have tried another Mach 64 w/4mb on the Intel board. I have also tried one of the Mach 64s in a Compaq 566 XL system. Neither of these trials worked. I also tried the SoftEngine F/X ADI drivers that ship with the Mach64. I set up vibcfg to use ADI drivers and set the correct rcpadi environment variables. This gave me the error: Display video hardware did not initialize I was wondering if you might have any ideas. <I was wondering what motherboard your using with the ATI card.

the ati is flawed heavily, it went back imediatly after 2 hours on the phone with teck support and it just does not work. i replaced it with a spider 64bbit 4 meg card and the other pentium with a genoa 64 phantom both installed in five minutes and with no problems at all. both are pci one based on the s chip the other on the seres logic(i can't spell) chip. and both under 400.00. and are fast. sherwood
