@chadti99 After good effort with 2 LuckyStar LS-486E rev:D boards and big stack of RAM modules I was unable to get DRAM SPEED = FASTEST (all other BIOS settings on max) to work stably outside DOS interactive graphics. Calling it a day, moving on. BTW, chadti99 and feipoa, what are the date stamps …

Does anyone have any experience using Sergey's ROM for >2 floppy drives? How does it perform on fast machines (shadowed)? Does it play nice with SCSI BIOS?

Can't really help with the jumpers but I do have questions: - Is that an 80287-10 next to 20MHz 286? This actually works? - There seems to be 1MiB of DRAM in sockets? I don't see parity chips for the on-mobo DRAM so it's a good candidate for those "new" 4MiB SIMM sticks? But then again it would …

Best video card is a Tseng ET4000AX It's definitely not. Overpriced and not that great when it comes to performance and compatibility. I can hardly find justification for using it in any vintage PC build - for faster machines there are better ISA options. For slower - as well. So it's a bit like " …

Best video card is a Tseng ET4000AX For hard drive the easiest thing would be a compact flash card, as mentioned earlier. Don't use XTIDE though, you're crippling a 286 with an 8 bit disk interface. Just get a CF to IDE adapter on Ebay for pennies and a standard IDE card

The XTIDE images as released DO NOT include a checksum byte, without which your BIOS will not load them. I have argued with the project maintainers at length about this and they will not listen to my pleas. You must configure the binary with the provided utility or checksum it manually using a hex …

For that reason I've always wanted a compact one, maybe even something you could cup your hand over like a big trackball (but it tilts on axes, doesn't spin). I've never come across anything like that. Modern Xbox/PS gamepad works quite well with Descent. this, after playing the original xbox …

I tried to adjust the Adaptec DMA speed from 5.0 MB/s to 8.0 MB/s, but the SCSI card was, upon reboot, unable to find the HDD and CD-ROM during bus scan. So I set it to 6.7 MB/s and re-ran CoreTest and DiskMeter . CoreTest 5.0 MB/s DMA --------> 6.7 MB/s DMA 2965.3 KB/s ----------> 3765 KB/s …

I have a POD63 that will not run stable at 2.5x33 or at 1x40, leading me to believe the hold up is the BIU, not the core per se. Think a volt mod would do it any good?
