If you don't get any ping with TCP/IP it either may be wrong selected cable type (BNC=COAX=RG58/AUI=DB9/TP=RJ45) or wrong IRQ. Use the card's jumpers or configuration tool.

You may try to move the environment vatiables to the END of autoexec.bat; at least below the TSRs loaded (but that just will free some space in UMBs).

You may try to disable sync negotiation in BIOS' device configuration. Just for testing purposes - to find termination faults - you even may try to not use that terminator then. Adaptecs surface test just transfers commands - you won't find termination faults with it. Does your Quantum Atlas IV U- …
Re: Does the Cyrix Cx486DX-50 actually exist?
Posted on 2023-12-21, 16:27
Honestly i still can't get why Cyrix would bother to bring out a dx50 at all. Lots of boards had proven to be unstable at 50MHz bus, while the DX2-66 was just as fast and perfectly stable with any half decent board. Intel was the pioneer at this speed so I get why they hoped chipsets would develop …

50MHz VLB would be insane. Just pre VLB some manufacturers released 50MHz local bus graphics systems, but everything was soldered on the board. Example https://www.vogons.org/viewtopic.php?f=46&t=35707&p=741806&hilit=vlb%2050mhz#p741806 May 1992 "Swan 486/33 DB, The blinding speed of Swan Direct …

In the meantime I think the HDD failed... It's a pitty because I think this computer had literally minutes of usage in the last 25 years... HDDs do not like to be stored without getting its platters and actuators moved from time to time. Perhaps you can try to rotate the uninstalled drive …

I had one of the last 20" CRTs. It was at the time where they got cheap because the production of 20" tubes had been stopped worldwide, but 19" and 21" have remained.

Apart from that it's a gen 4.5 CPU, basically a 486 with some Pentium instructions and techniques shoehorned in. I didn't know it included new instructions. Do you know which ones? Would it be instructions like RDMSR / WRMSR / RDTSC etc? CPUID Some things you won't expect on a 486 like branch …

Uncommon cache chips, indeed. 5C6404-15 16Kx4 15 ns because of 40 MHz It looks like it is layouted for one cache bank with 8 chips. For me it looks like you need 10 64kx4 chips.
Re: Suggest SCSI (again) over 233MMX

Tbh, the linear throughput of a HDD is generally its least relevant spec. For HDDs, seek time is king, which is why fast-rotating SCSI drives respond better than any PATA drives, even if they run on ATA133 bus. 20MB/s is probably more than an OS running on a P233MMX could handle, and even at that …

Then it is just a matter of whether you want to use internal SE wide device and internal LVD device at the same time. However, the 29160 is superior then. But check the PCI slots. The front side (away from the bracket) must have a kind of space so that the 29160 with the 64 bit connector will fit. ( …

So you suggest 29160? That depends on which connectors you want to use. 19160: External SE Narrow 29160: External LVD 29160: Internal SE Wide 19160: Internal LVD 29160: Internal LVD 19160: Internal SE Narrow 29160: Internal SE Narrow So if you like to use old SCSI cases or external SCSI ZIP drive, …

Yes, you can use that Initio SCSI card. But you'll be limited to the speed of Narrow Ultra SCSI. That is 20 MB/s. Yes, there do exist SCA-to-68-and-50-pin Adapters. However, some of those adapters may not have a connected DIFFSENSe wire. You perhaps have to solder a connection or play with Force-SE …
