Re: Cirrus Logic CL-GD5429 vs Trident 8900D - disappointing
Posted on 2018-05-21, 16:57
Doesn't this 9000i have 1MB? Actually not, the 9000x are the low component version of the former 8900c that Trident release in order to compete better with AcuMOS graphic chips. All of them do not support more than 512KB http://www.vgamuseum.info/index.php/component/k2/item/445-trident-tvga9000i-3 …
Re: Which memory manager is better? Memmaker, QEMM or 386max.
Posted on 2018-05-15, 16:16
There are several alternatives to QEMM and 386max. Personally I had good results with Helix Netroom. You can try Memory Commander too, but, unlike Netroom, I do not have good memories of it.

Re: PC Chips 286 M216 Motherboard

It's a limitation of memory speed. A 25Mhz. 286 will require very fast DRAM modules (<50ns) or a small amount of cache. Cache is done using SRAM memory chips that don't need refreshing and are much faster (<25ns). You have a calculator here: https://matrix.home.xs4all.nl/calc/waitstates.html …
Re: Why is MS-DOS 4.0 disliked compared to 3.0 and 5.0 and onward?
Posted on 2018-01-28, 18:13
Here is a in-depth analysis of it: http://www.os2museum.com/wp/dos/dos-4-0/ It was the first DOS version not designed with XTs in mind and, although it can be installed on floppies, it actually requires a HDD to be useful. I use PC DOS 4.0(1) on my 286 and MS-DOS 4.01 on a 386sx. It only needs about …

Re: Help with Trident 9000B 16-bit mode
Posted on 2017-12-31, 08:12
I have a Trident 9000B on a 386sx (@40Mhz) too. The Trident 9000 is the low component (cost) version of the 8900C. You only have to add 3 more chips to have a complete (S)VGA card: BIOS, memory and RAMDAC. The 9000i integrated also a RAMDAC so you need only 2 more chips. 8900CL and 8900D had FIFOs …

Type 47 allows you to define custom HDD geometries so you actually don't need the controller BIOS (at least not for HDDs <= 504MB). You can try the following: 1) Ensure that the HDD is clean (no partitions on it). Maybe you partitioned the HDD using a geometry different that the one the controller …
