Not sure if this will help, but can't you just manually edit the NG2003 bootable diskette to include the required drivers https://support.symantec.com/en_US/article.TECH107936.html That is a good point. I just checked my Ghost diskette and ASPI7DOS.SYS is not included. I've added it to the diskette …

Can you use a Linux boot disk on your 486 system? Even a minimal system, as long as it has the "dd" command and drivers for your SCSI card. One I can think of is an older Slackware boot/root disk set such as https://mirrors.slackware.com/slackware/slackware-3.6/bootdsks.144/aha2x4x.s for bootdisk …

I don't have had problems with my EISA 2740W using ASPI7DOS.SYS and DOS based Ghost 2003. My translation is C-255-63. I don't have created partitions beyond the 8 GB limit. What translations are in your partition sectors? It is supposed to use 255 head / 63 sector. When I copy the HDD using an …

I have this Adaptec AHA-2842A VLB SCSI card in a 486. I ran out of HDD's during the build, so I used an Ultra320 , 146 GB drive and made two 4 GB partitions. Well, now I want my 146 U320 HDD back for a new build. I have a noisy 73 GB u320 drive I'd like to clone the data onto. When I hook both HDD's …

The 56 vs. 59 MB/s for RAM read is the edge I was talking about in favour of the SiS 496. I want to say that the UMC had a slight edge in L2 cache read speed, but don't recall. Are you able to run your system with 3-1-1-1 and see what the L2 result is in cachechk? At 60 MHz FSB, I had to use 3-2-2-2 …

155/84/46 for 2-1-1-1, and I assume that "DRAM Faster" = 1ws/0ws? I get 155/76/56 for 3-1-1-1 and DRAM 0ws/0ws. Data on page 4 of this thread. Did your system pass HIMEM with these settings? Will you be able to install Windows and run a game? It is fairly easy to get faster settings going in DOS. …

The POD generally got a bad rap for being expensive, late, and with specs changing. It was also widely considered slow in everyday tasks at the time. It does alright in games, obviously. Anyone have 3D gaming experience with a POD83 from 1995-1998? If it was your main system at the time, it would be …

POD = Pentium Overdrive. It is a Pentium CPU which fits into a 486 motherboard's socket 3. 83 = 83 MHz, 100 = 100 MHz.

I decided to measure and include results for the situation whereby the Am5x86-160 is run with a 26.7 MHz PCI bus instead of a 40 MHz FSB. This might be done deliberately by the user for expansion card compatibility, or by absolute insistence of the BIOS. Concerning the latter case, the PC Chips M919 …

The colour is agreeable though. https://www.digikey.ca/product-detail/en/cnc-tech/610232/1175-1715-ND/4924061 Anyone have an online source for this stuff in smaller rolls?

The IHS definitely felt a lot heavier than solid aluminum. While waiting for my fan, I've ordered some MX-4. I read several reviews on the different pastes and this seems to be decent. Plus, I needed to add something small to my cart to get free shipping on amazon.ca. Will use this on the IHS and …

Heh, makes me wonder if Quake could be optimised for the Cyrix 5x86 such that it out performs the Pentium. If you look at the chart for Descent 2, the POD83 is third from the bottom, yet in Quake, the POD83 is at the top. Also makes me wonder if any software was optimised for the cx5x86. This CPU …

To make out-of-order execution more efficient, these x86 instructions are translated to an internal representation. This can be seen as another type of machine code. You could say that modern x86 CPUs are 'emulating' an x86 instruction set by translating the code on-the-fly. These internal …

I'm impressed you could even get 7FPS in Unreal with a 486. The frame rate feels a lot faster when playing the game walking through that crashed space ship, if that is what it is. It would be nice to see how other systems perform. I have run things pretty well optimised and suspect not all other …
