Hello. Anyone there? Anyone seen my posts? Anyone leaved a comment? Too new to count as retro in my opinion, sorry. The machine could run Windows 10 x86 maybe :D In fact I tried to run Windows 10 on a Athlon 64 machine, it really works. Awfully slow though, because I used a SATA conventional …

To be sure that it's not a memory issue, you can run the MMX with FSB 100 either with 200 or 250MHz, too. All 233 MMX that I tried could run with 2.5 x 100.

Try setting the voltage to 2.1V

A small update from my side: Unfortunately I could not find the ECU disks for the ProSignia ... Also I did not install the system partition back in time. Well with the hints in the previous postings, I found in reasonable time the "Compaq System Configuration Utility VERSION: 2.58 Rev A" and "Compaq …

Yes, obviously it is 1:1 here, he used a DX-50 and there is a 50MHz oscillator :) I agree, it's a very cool board, it cries for upgrading the cache :D The cache SRAMs that are now on the board seem to be quite slow with 25ns, I think too slow to do 2-1-1-1 timing on 33MHz, maybe just fast enough for …

That board seems to have a 50MHz crystal oscillator. To run a DX2-66 you need a 33MHz one. So if you just put in the DX2, it is clocked with 50MHz, internally with 100MHz, no 66MHz type can do that.

Congratulations, I own two of these systems myself. Along with many more Compaq servers including the 1500 and 5000. As you allready found out the box does not have any usual BIOS, instead allmost everything is configured by the ECU (EISA configuration utility). This can be started from floppy …

I ordered now 2 modules for 48€ in total, each with 24 chips similar to mine, so I hope I will get my 112MB RAM in total soon 😀

Wouldn't throw in that towel just yet, could very well be that generic PS/2 class 72-pin FPM parity SIMMS could be utilized here, instead of having to hunt down the exact parts. That's true: I opened the case, to check what 32MB module is inside: It's a Kingston KTC32K/PS It has 14 chips on the …

Googling was actually a great idea 😁 " 32MB Compaq ProLinea/ProSignia/Presario Parity SIMM 149147-001, 190748-001, KTC32K/PS " That seems to be the right memory, not so easy to get as it seems. I need a seller inside the european union

The computer still works like a charm :), but honestly spoken I never did something with it, I only installed Windows 98 SE back in time. :D Some Photos: IMG_7298 (2).JPG IMG_7299 (2).JPG IMG_7304 (2).JPG IMG_7306 (2).JPG IMG_7309 (2).JPG So there is an IBM harddisk inside, Toshiba CD ROM and a …

I did some more work on it last night and got the system partition created and the ECU / "bios" installed on it. Next step now is to find my MS Dos 6.22 disk that I have somewhere... I think I have one of those Smartstart CDs here together with some documentation covering the Proliant 1500 and/or …
