This has been discussed a couple of times before. The 2.5x multiplier was indeed planned at some point, and made it into the datasheet, but it was not implemented in the final version. It would be interesting to see if anyone has DX4 prototypes that still have it. Supposedly, the reason for the 2.5X …

This is the UMC 480 chipset, isn't it? Weren't those super common on 386 boards? Try the BIOS from the FX 3000.

I’m of the impression that Realtek makes shit based on all the problems I’ve had with them over the years. Supposedly some models are better than others, but I must have the best luck because I always get the lemons. Admittedly I don’t buy expensive laptops. My last one was an Asus E202SA. Whatever …

Re: Is having 386 with 486 chipset is bad?

I think 25mhz was the cutoff for 0ws cacheless 386s. There are some true 386 boards (with chipsets designed specifically for the 386) which were made in late 1992 which have all the bells and whistles of the hybrid boards. These are the most desirable ones in my opinion.

The good true 386 chipsets had better main memory thoughtput, while the hybrid ones tended to have better external cache design. Things kind of even out with regards to overall performance. The hybrid boards have the advantage of almost always supporting the 40mhz bus, 4mb SIMMs and cyrix support.

Too bad utilizing all of the EISA slots isn't really feasible outside of server use where you might have multiple NICs and SCSI controllers. I built my MCCI SuperEISA based system back in 2004, and most of that time only 2 EISA cards were installed. With the VLB slot, there's no need to use EISA VGA …

ESDI was a relatively rare and shortlived standard. I've come across an ESDI drive and controller exactly once in the last 34 years I've been into vintage PCs.

They were the low tier producer with meh fab capabilities, Europe was much friendlier with the slower clocks so it was probably a financial thing that the fast IBM/Cyrix chips stayed in the US and the ST produced chips with yield issues became the harder to market PR133 and down thus being sent …

I believe my 5x86c is also from early 1996, and it’s 2x/3x s0r5. It seems 3x/4x was somewhat common with the ST branded chips, but it seems most of those went to Europe…I never saw any in Canada.

Can I just swap that one with one from another 486 board? I'd say for boards made after 1991 it's usually not much of an issue. Sometimes the OEM assigns the turbo function pins of the KB controller differently. If you have access to MODBIN or AMIBCP it's possible to correct this. In any case, it …

Don't laugh, but I find a good indicator if the drive is 360K is if its activity LED is red. If it's green I'd swear it's a 1.2MB drive. A definitive answer is if you hook the drive to the PC and specify it as the wrong format.. typically you'll get a "diskette drive error" right away during POST. …
