So yeah the BIOS looks cool because it's in color, but I'll stick with the AMI because it does everything better. Other than the turbo switch/LED, what does the other BIOS do better? One major advantage of the color BIOS is that it allows more granular setting of EMS memory size. In particular, it …

If the VLB versions are any indication, the C and CD versions use the same BIOS.

Sorry for bringing up again this old thread. I'm trying to get one of these running, but it insta-reboots my 486 after it has counted RAM and told me "drive configuration changed". It also will not get past POST (except if I let it time out) if any disks are configured in the system BIOS (with other …

Tested on a different MX-chipset board (which is the same chipset I have in the first machine I reported about). It inits, but only after one or two SLAM attempts. Typically it needs two the first time after boot, and only one afterwards (or after a warm boot). This is with a 386DX CPU; the other …

Sorry it took me a while, the test bench was busy with another project of mine :-/ EEPROM reset successfully. Page-write command sent. The output of subsequent orphinit /vd is *exactly* the same as the one I posted earlier (forex), byte-for-byte, confirmed using FC (DOS file compare). What now? :)

What do you mean won't work with solid state? That's what I'm using .. Unless you mean something else than CF, like PATA-SSD? But aren't you using an option ROM for IDE support and not relying on the C&T alone? Ah sorry, I thought "everyone" used some kind of BIOS to get larger drives these days. I …

Tried on a different 386 board now - FOREX/UMC based. Debug output attached; this time it seems like it can see the ESS - but not in the PnP card list, and after trying a couple of times it gives up. Interesting times :)

The 286 on which it *works* is a C&T SCAT board, 12MHz CPU. The 386/486 on which it *fails* is linked in my post above. If I have to rip that machine apart again now and replace the motherboard I'm going to be more than a little bit annoyed (but not at you, obviously) :D

I just plugged that C&T BIOS into the JSC board after I got the 72pin socket soldered on, and it works as expected. However, neither turbo switch nor LED seem to work at all. Currently got 3MB Extended and 4MB Expanded memory configured. And 0-ws and the works. Boots nicely from CF. I have a Promise …

So the card works in a different machine - I guess this is hardware-dependent then. That's a bummer :( Also FYI the Ctrl port of 120 as seen in the log is because I forgot to change it back to the default after experimenting with something I found earlier in this thread (or on a different orpheus/ …

The full debug-level output from ORPHINIT. The easiest way is to issue the command ORPHINIT /v d > ORPHINIT.TXT then post the resulting ORPHINIT.TXT file. Attached. Without a baseline I don't know how this should look (I'll test my other card in another machine in a bit), but one thing caught my …

Hey, thanks! Happy to ping-pong :) But I'm not physically at the machine until later today. If you're on IRC or Discord or the fediverse or something, we could do "real-time" ping-pong if you'd like. Something strange appears to be happening here. If you don't mind a little bit of collaborative, …

I've just started playing with my OrpheusII, and I'm getting "Unidentified chip found; quitting.". Using default .ini file. This is a non-PnP system. Only other card installed is a 3com 3c509 (Etherlink III); I can try to change its IRQ and port (currently 10 and 300), but doubt that will make a …

I didn't even try the switch. It's not something I use a lot :) I'll do that when I get the boards back. I'll be installing a 4.something volt battery once I get around to measuring properly. The onboard battery seemed to be leak-free but I'm pretty sure it has no juice left.

I just received a couple of these boards too. And I have a MB-1212 BIOS that I couldn't find on TRW; I uploaded it there yesterday. Attached here if anyone wants to play. It's a *LOT* nicer than the ones that were on TRW until now, and works nicely with this wonky board too, it seems (though I have …

This is an awesome board. It'll work fine without the proprietary VGA. Performance is really quite excellent. That other eprom is the recovery bios. There should be a jumper to activate it.

I just tested two additional BIOSes on my board. -Dolch PAC60 uses an OEM version of A.I.R. 486EI AMIBIOS. Seems to be from PCB revision 1.5x, and doesn't have support for DX4. -Abit AE4 uses Award Modular BIOS v4.20. Amazingly this one will properly detect the 1MB cache on my board, but only 32MB …
