The Deskpro EP is a pretty generic machine for an OEM box. It is allmost stock ATX, so feel free to swap. Lot of other OEM use much more proprietary parts so swapping any generic parts is allmost imossible due to incompatibility.

You are right with the Compaq boards. Do not go for one of these boards, try to look for a complete system. The Deskpro /M and Deskpro /XL were quite common a while back. As others mentioned before look for a EISA/VLB board if you want decend video, because EISA graphic cards are really hard to find …

Usually it is no wizardy setting up an optical scsi Drive in dos if you have the drivers handy. Easiest is if you have an adaptec controller (host bus adapter) and a copy of EZ-SCSI. Just run the setup or install script and you are done. But doing it by hand is not difficult either: - First you need …

Are there any other owners of OPTi localbus systems around? I own a Galaxy local bus board using the same EISA Connector for its proprietary local bus. It is probably OPTi 498 based as well and came with an S3 based video and a DC880 caching controller. Am I right these things are quite rare? Never …

Did you try to disable the cache via BIOS or jumper? If the cache is really bad there is no wonder you run into memory errors still using it, or are you getting the himem.sys error despite disabling the cache? You can visually inspect the area where the cache chips are soldered and try to clean it …

The reason the adapter is not shown in the SCSI configuration is due to the fact the topic can only be used with IBM SCSI adapters. If I remember right even an Adaptec 1640 can not be configured under this topic. I am not sure if you will be able to run a HDD or even a flash drive from the Mountain …

SCSI is a specified standard. So any SCSI device compliant to the standard will work on any compliant adapter. There is no reason it should not work. Just some UNIX workstations like RS/6000, hp 9000 and SUN use a different sector size of 2048 bytes for optical drives instead of 512 bytes common on …

Er no, the extra chip only tells you it uses some form of parity. For regular parity you need one bit extra for every 8 bits, for ECC you need two bits extra. Doesn't look like simple parity - 28-pin chip. Agreed, but it's that - and not the simple fact that it has one more chip - that potentially …

There are of course memory expansion boards around, you could use as well. While 1.2 MB drives can read the 360 KB disks just fine, the tracks they write are too …
