Digital Prioris XL 5200 memory issue
Greetings,
I have great problems with this machine. It is Digital Prioris XL 5200 with dual P200 P54C (Socket 5) and archaic Intel Neptune (NX) chipset. The problem is - machine sees 256MB of RAM during post, but: Linux, FreeBSD and all the programs from Hiren's boot CD (Astra, Aida and even simple "mem" form DOS) see only 64 MB Windows 2000 Server sees 96MB There's 256kb L2 cache, and if I recall correctly, it is suppose to have 11 bit tag, that is, machine should be able to cache 512MB of RAM in write back mode! Thus, it puzzles me why can't I access more than 96MB in W2k and 64MB in all other OS. Google didn't provide any quality troubleshoot. Any thoughts or experiences? -- Everything will be okay in the end. If it's not okay it's not the end! |

I actually owned a Prioris until recently Mine had dual pentium pro cpu's. Anyway I don't have it now so I can't check... but look in the bios options and see if *maybe* it's set to OS/2 as the operating system as OS/2 usually has it's own special settings if RAM is over 64 megs. As a matter of fact I'd check all bios settings regarding RAM. If nothing turns up there...run a RAM test, just as a precaution |

I actually owned a Prioris until recently Mine had dual pentium pro cpu's. My condolences. God damit, I'm so ****ed off I could find Ken Olsen and roundhouse kick him 'till he drops dead! Anyway I don't have it now so I can't check... but look in the bios options and see if *maybe* it's set to OS/2 as the operating system as OS/2 usually has it's own special settings if RAM is over 64 megs. As a matter of fact I'd check all bios settings regarding RAM. If nothing turns up there...run a RAM test, just as a precaution Ok, I managed to solve it, and here's the thing. This Prioris is EISA machine, and those machines *generally* have ECU and SCU disks, and *all* configuration is done via those (IME). However, this particular Prioris has very capable "local" (so, without need of the disk) configuration utility, that seems to work, since changing options such as caching, enabling SCSI controller and such work flawlessly and stay remembered. Heh, but now's "funny" thing - when you add or tamper with memory in any way, you *MUST* run SCU disk and merely *save* the configuration. Afterwards, it works perfectly. Well, that's about it. I hope this helps someone... someday... maybe. -- Everything will be okay in the end. If it's not okay it's not the end! |

Digital Prioris XL 5200 memory issue
Careful with Ken Olsen there. He's very long in the tooth now. Anyway, it's
not Ken's fault that you need to run the EISA configuration utility, a half-baked idea matched only by the IBM MicroChannel Utility, from which the ECU was copied. Blame the 3-humped camel of the EISA committee: Compaq, HP (when they were separate companies), and whatever were the other major PC manufacturers of the time. I mean WHY run a diskette configuration utility when the configuration coule be handled by the BIOS setup or by autoconfiguration of the memory? The Neptune chipset was very interesting with its early support of 512MB of memory. Intel's Triton chipset backed down to 128MB max, so that the Pentium Pro server systems would look better at 512MB with the early 440 chipset, whatever it was called...

Careful with Ken Olsen there. He's very long in the tooth now. Yeah, he's lucky enough Chuck Noriss didn't try to configure this machine... Blame the 3-humped camel of the EISA committee: Compaq, HP (when they were separate companies), and whatever were the other major PC manufacturers of the time. I mean WHY run a diskette configuration utility when the configuration coule be handled by the BIOS setup or by autoconfiguration of the memory? Running a floppy is not so awkward - EEPROM's were smaller than today's and many configurations for EISA cards could fit on a floppy, not to mention that these configuration utilities are usually well documented, so although I despise floppy drives, I wouldn't have been surprised if i had *only* needed to run SCU. However, this one is for the books! If you run that embedded configuration utility, you can handle configurations up to 64MB RAM. Obviously, higher amounts require SCU. Incredible... -- Everything will be okay in the end. If it's not okay it's not the end! |

I hope this helps someone... someday... maybe. Yes , setting up those EISA configurations are a lot of fun. I still have an IBM PS/2 that's MCA and it also requires those setup floppies to configure the bios...but I've kept my PS/2 because at least I can carry the darn thing. I don't know how I got that Priorus into my house without any help... but when I found someone who was willing to haul it away...I figured it was time to get that boat anchor out of here!!!! |
