lol, ok. I need some time to dig through the channel logs as most of the woes are now in the past.

What version of the MB-8433UUD are you using? I've had better luck with the later v2 (9620+ datecodes on chipsets), v3, and v3.1 boads. Ensure your cache isn't mixed mode. And use a PCI HDD controller card and no CF. I've had issues with CF on this board, but I don't recall all the particulars …

I have been sticking with the release repositories and am not entirely unfamiliar with Linux. If you are interested in my struggles, I have been noting my struggles on an Undernet IRC channel and simply dumped by curses into there as a means to cope with this usability nightmare. I use a lot of foul …

Can you clarify if you were using EDO or FPM?

Replacing the clock crystal doesn't always work as it messes up the timing of other systems, most notable will be the the floppy controller not working properly. Disable onboard floppy controller, run an ISA floppy card problem solved It's not very elegant though. But if you are OK with this type …

I'm in the process of upgrading my 5 general use home computers from XP POS2009 to Linux. There are two desktops in the office (one Mac Pro 2,1, one Operton 185), two laptops (T61, X201), and my garage/mechanic desktop (Prescott 3.8 GHz P4 640 I think). It was the Windows source code leak which …

The ver:2 manual I wrote is here: http://www.vogonsdrivers.com/getfile.php?fileid=946 BIOS settings should be noted in the back of that manual. I do need to update the manual to include some more detail on the cache mod, but I'm concerned that I never will have time. My home life is a mess. I'd like …

Yes, thank you. A gorgeous mod esp. with the Intel heatsink installed. Were you able to do the mod without removing the re-gluing the heatsink? I found it is just doable without removing the heatsink.

I applied @feipoa's mod to the CPU. With few small improvements. Didn't cut the pin, but only unsoldered and bent it upwards, making sure it does not touch the heatsink. Inserted a piece of insulator to form a bed for one of the diode legs. Precisely bent the diode wires to fit exactly where i …

Oh I wish. But like you, I have no time now, not even to assist with cache testing. Stand by...

As I have recently been converting all my daily use machines from Windows to Linux, I was left perplexed by the lack of a "Device Manager", Astra, Everest, or hwinfo type of utility in Ubuntu. While there are a few add-on packages, they are very lacking in detail. I was wondering if there has been …
Re: Why are 3Com NICs in such high regard?

Which Linux distro do you use on 486 PCs (this one has no CPUID instruction)? I was referring to a little more recent benchmarking I had been doing with Ubuntu 16.04 LTS on an Opteron 185. I haven't had Linux on a 486 in some time now. For the full package, Debian 3.0 (Woody) ran OK, but for …

Are you able to test it in Linux using iperf? Seems that when I test stuff in Linux it approaches the transfer spec, e.g. my gigabit ethernet benches around 950 mbit. Did 3Com ever make a gigabit product?
Re: Multi-lane upgades for USB 3.0 and SATA 3.0 on PCIe 1.0a
Posted on 2021-02-14, 16:54
From what I can tell there has been no change in max power delivery on any of the PCIe standards and that seems to be beside the point. I'm not sure what your point is; I am trying to determine why your USB 3.1 card explicitely states it needs PCIe 2.0 to function. Does your card have a SATA or …

I was unable to find a photo of your specific SW-2042 V0.5 card. So I was only guessing that your card was missing the SATA/MOLEX power connector, similar to how that Asus card is missing it. The Wiki post I pasted is likely referencing cards without the SATA/MOLEX auxiliary power connector - so …

I doubt that the PCIe2.0 requirement is one about power. FYI, from wiki: PCI Express 2.1 (with its specification dated 4 March 2009) supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same …

Sorry, must have got you mixed up with the other poster. Thanks. The descriptions mentions 5 Gbps per port, which is the coded datarate for USB 3.0 (3.2 Gbps for the uncoded/usable speed). This implies to me that each port gets a single lane only. Bang for buck, this one seems better: https://www. …

You have this card in person? Are you able to follow the traces to see if Lanes 2 and 3 are connected to the IC? Could the PCIe 2.0 requirement be one of power? If so, the Asrock card (shown above) has external power.

I read that quality SATA 3 SSD drives can reach 560 MBytes/s in real tests. With PCIe 1.0a, I would need to utilise at least 2 lanes to get close to this. Real world, uncoded, USB 3.0 should reach around 400 MBytes/s, assuming the external drive is a capable SSD. I would also need to utilise 2 lanes …

I have the Adaptec ASR-6805T, so if I have time, I might try to determine if a single SSD can exceed the PCIe 1.0a single lane bandwidth. I'd like to understand if there is a technical limitation to using more lanes per device. These x4 cards, using just 2 lanes, is curious. Why not connect the …
