Here is the location (I think) for the unpopulated RJ45 port, and the onboard LAN IC: Filename 480817C5-51E2-4E95-9B3E-3D9C2D0DE13E.jpeg File size 315.02 KiB Views 24 views The missing cache, I believe, would be here: Filename B1F2CB6B-75D0-4D48-9A08-927A85F85122.jpeg File size 333.4 KiB Views 24 …

I just acquired this UMC-based SBC 486 motherboard, from eBay: D3D2D857-B40F-4F1C-AE39-3871DFCCC259.jpeg And here is the back: 646FD4AF-CB41-4E38-AE9E-05CB9B64DBF0.jpeg It came among with this attached VGA card: 219FD2B3-76BD-4FED-8A8C-CF9650F00A1C.jpeg The only label on the board is INS-UMB486DX/ …

There were ISA microATX motherboards that people put in low-profile cases. I’ve seen quite a few of those. I dunno if any major OEMs created systems with low-profile ISA slots, in any significant numbers, though. - Alex

I just tried setting the CF card up using PCem, using a generic AMI BIOS 286 board, and dd’ing the resulting image to the CF card. The drive starts to boot, on the PC40, but then hangs. Sigh. Geometry must be too different. I had both set for drive type 1, in the BIOS, which should mean straight CHS …

So, I've tried Drive Manager v7, v6.03c and v4.5. 4.5 runs, but only seems to support a very small list of drives. v6 and v7 both give a stack overflow error, on the CBM. I also tried EZ drive 9, and it similarly crashes. I'm assuming that they are running out of memory. Any suggestions of software …

My drive controller is standard IDE, so there should be nothing unusual. The ramdisk thing explains the problem that I have had, with Ontrack. Horun, if you'd share (or better, upload to VogonsDrivers) the versions of DrivePro and Ontrack DM that you have, I'd appreciate it. I'll take a look at the …

So far, I’ve tried installing locally, from DOS, on the CBM. I’ve also tried installing it in a virtual machine, in VirtualBox, with raw device mapping. I thought about using one of my other machines to do the installation, just this morning. Given the way that the overlay software works, I’ve found …

All, I’m trying to setup a drive overlay on a 4GB CF card, for a Commodore PC40-III (286). The issue is that the machine only has 1MB RAM (see my other thread, I’m still looking for RAM expansions for it), so most of the common drive overlay software won’t work. Does anyone know of a drive overlay …

With ‘w1’ jumpered, the card appears nowhere in the 16MB address space. I’ll set the jumper to ‘w2’, and try again. I also noticed another jumper, near the backplate, labeled ‘w4’. It’s hidden by the tantalum cap, in the picture I posted, above. I’m not sure what that is for, either. - Alex

Thanks for the notes. The jumpers are labeled ‘w1’ and ‘w2’, very likely indeed picking which window to use for EMS. I’m still trying to figure out what the board is, so I can look for the driver for it. I had guessed that being made by ALR would make it easier to find, but that appears not to be …
