Little update: I tried with different IRQ(12) and now the card can see my CF cards. Now fdisk is unable to detect fixed disks XD That would suggest that you have another IDE controller on IRQ 14.. Any sound cards or whatnot that has been configured to use IRQ14? I know at least a couple of my "no- …

Here you go. It should be uploaded to vogonsdrivers but I need to dig out my FTP credentials again.. This ZIP contains three dumps, all of them look like version 2.20: - From a Longshine LCS-6941 with 64k chips, M27C512 - From a Promise DC4030VL-1 with 64k chips, M27C512 - From a Promise DC4030VL-1 …

I just bought a DC-4030VL-1 in physically good shape, but without ROM chips. Have you managed to find any working BIOS/ROM for the -1 version? Hey, welcome :) I can get you ROM dumps, but not with LBA support, sadly. So it won't be useful unless <500-ish MB is enough .. "Someone" should try to add …

Just want to say that this card, with PCmidi add-on and McCake WB module, is absolutely effin' brilliant. My 486slc2 has this combo and a GUS PnP and it's just .. a dream. Thank you! (Had to attach some pics.. the mt32 gets a bit hot so I added the tiniest fan I've ever seen ;) )

So I gave up on the AIR 486ES board, and tested with an ECS mainboard .. And now things work as expected, across the board. I repaired the DS1225 on the AIR board (used for EISA config storage), but despite being able to survive longer power outages, it changed nothing. Using a much older - 2.01 - …

I've now attached a new battery to the Dallas DS1225 that seems to have been flaky; this hasn't made much of a difference. Although I'll say that I'm now able to have config changes to both the Adaptec and the SMC NIC in the machine "stick" through reboots warm and cold. However, in a very un- …

Ok I can confirm my card also works with 2.x BIOS; it just doesn't like AT28C256. With AT29C256 it loads the BIOS just fine. I still can get the card to actually *work*, but that seems to be due to a dad EISA config storage DALLS, which on this board is separate from the CMOS settings, it seems.

Ah, it says "Host adapter configuration error" - no matter if I use old 1.1 ECU files or the newest (2.12).. The 2.11 BIOS doesn't rear its head at all.

I dumped the odd and even sides. I also merged the two after dumping to verify that data was read. I could clearly read ASCII data that makes me think both dumps were a success. I'm not very versed in lots of chip types, but I think the third chip is probably not a PROM of any kind. If it is I …

Image files are owned by root:root and permissions are 644 (only root can write them, group and others read-only). Netdrive uses dedicated 'netdrive' account to run. And traversal rights (+x) on parent directories, and read on the image directory? Stared myself blind on that kind of thing more …

For the NEAT chipset there's a DOS tool to set the various fancy chipset registers, even if the BIOS does not expose them. Is there such a tool for SCAT as well? That would make me less dependent on the BIOS I'm currently using. There's a DMA-related setting the chipset registers that isn't exposed …

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 …
