Hello. Quick question. Can't find manual for that adapter, but it's seen larger drives only as 8GB.
I tried three disks 18-36GB and it's 8GB only.
I'm on K6-2+ ss7 mobo. Winodws 98. IDE drives there 80GB and 120GB, but that's mobo built-in.
Just wondering if it's just limitation of this adapter? Or what should I do?

Believe this may be a hard disk capacity limitation on these cards, as their extended translation routine only supports up to 8GB per disk

That card looks like it could be an OEMmed version of the Advansys ASB-3940U .

That's what I thought initially. Just thinking If It's possible to update firmware or change that thing

It's not really firmware fixable - SCSI extended translation is there for physical disks > 1GB under DOS, upto a max translated capacity of 8GB. If you want the full capacity then (if you can) disable extended translation thru the SCSI BIOS menu and use driver access in Windows.

This particular adapter was commonly sold as the iomega Jaz Jet PCI Ultra

Can you post a good picture of the card ? I have a few 1998/1999 BIOS for Advansys based cards but they are chipset AND flash chip specific.
Only for certain Advansys based adapters with Atmel Flash AT29C512/AT29C010A or Winbond Flash W29EE512 or SST 29EE512/29EE010 bios chips.....
Your card being designed for the Jazz drive may never have had a 8Gb+ BIOS upgrade, no need since it was not designed for that but there is hope.
If the chipset and flash chip are supported it could be flashed but no guarentee it will work or worse could bork the card...
side note: I tried flashing some OEM Adaptecs (with adaptec flash and bios) and some worked out OK others the flash util refused to flash them but they still work

Yeah I saw that one with ASC3050B chip but another had a 3150C chip number and the fcc ID was 940u not 930u. Seems there are a few variants and the flash chip type are unreadable 🙁
Though that one has bios sticker 3001-0041 where the other has 3001-0029 which am guessing the last part could be bios version???. https://i.ebayimg.com/images/g/qG4AAOSwRTJeenvw/s-l1600.jpg

There is a BIOS available from here : https://web.archive.org/web/20060512193357/ht … ow/utrpcmac.bin From the name, I believe that it s compatible with both PC and MAC (could be wrong about that) and what I believe is the flasher is here https://web.archive.org/web/20060512193302/ht … ow/FastUltr.zip
More drivers are available here : https://web.archive.org/web/*/http://initio.c … vansys/narrow/*
Context leads me to believe that this BIOS is compatible with several Advansys PCI SCSI adapters, but I cannot be sure of that (even less sure about OEM variants like the Iomega one).

EDIT : Additionally, the ROM chip on the Iomega card may not be flashable either at all or by the card itself . A replacement chip or flashing externally may be required and, as mentioned before, no guarantees that any of this will work on the Iomega card (or fix any disk size issues).

Thank you so much! I'll try. I have two cards like that. Yes exactly as on Amazon link. 3050B chip
Well... It's what I have. I'm using 18GB for a moment as 8GB. Better than nothing 😀

Thanks ! Added to my Advansys archive. Attached the 3 .BINs I have along with the flashers and readme's. Those came off a Iwill cd for their scsi products based on Advansys chips.

Ok, I understood it's complicated and probably limited to just use Zip and Jaz storage which never exceed 8GB. I went ahead and bought Adaptec aha2940w over eBay
No matter what disc I'm connecting to it I'm getting this message, when I try to check or format disc thru BIOS.

However by BIOS time post it's detecting it and saying Make and Model and C: (80h), but then not in DOS (FDISK fails to run after asking about large discs, just quit) nor in Windows (exclamation point in system properties) works
Any help? Sorry I'm new in SCSI. Connecting hard drives thru converter of course (50 pin + power) to HDD connector SCSI-3 I believe (all in one)? Again with Jaz SCSI adapter everything works like a charm, just limit to 8GB.

Did you scrub any translated partition / format created by the Jaz SCSI adapter before you attached it to the Adaptec - if not, it may be a mismatch in how the extended translation scheme is being interpreted

Can you post a screenshot of the Advanced Host Adapter Settings on the Adaptec - this should include the current state of the adapter BIOS, extended translation scheme & Int 13 support

Are you planning to boot from the SCSI drive, or just to add additional SCSI storage space

Also, the 8GB limitation under DOS applies equally to the Adaptec AHA-2940W - again, if you want access to the full capacity then disable extended translation and use driver access instaed

"AHA-2940W Product Specifications - Hard Disk Capacity

Extended translation scheme supports up to eight (8) Gbytes per disk"

Yes only Adaptec BIOS 1.34 or above supports 8GB+ in extended translation, v1.23 does not (for 2940u/40w/40uw). Also Adaptecs BIOS update to 1.34 only works on retail and certain OEM models with flashable roms, not all Adaptec or OEM can be flashed with it.

Can I upgrade?
The point is with Adaptec I can't even access to the disk from any OS... Can't format in Bios, can't check. It's saying the make and model and C: (80h), but in fact no disk can be seen after boot. Fdisk failed to start

That depends. I have upgraded one 2940U to BIOS 1.34, the other will no upgrade from 1.23. Both are board # 916507-00 rev D on back.
Both cards look nearly identical except: the upgrade one has a SST 29EE512 EEprom chip and board dated 1696, the other has Atmel 29C512 EEprom chip and card dated 0996.
Other note: the flashed one has a number embbeded in the white band top left of 50pin starting with BEOF.., the other has just a sticker on the back with a BE0D number and no number printed on the white band on front.
I believe the second "unflashable" one is an OEM Dell card. Both cards EEPROM's are flashable but Adaptecs flash util will not flash the supposed OEM card.
The EEPROM is near the LED and 4pin led connector with a small yellow sticker on it. I flashed all my Adaptecs years ago but put a note on back of the unflashable one so I would know.
added #1: Also you cannot flash 2940U to bios 2.20 that can be flashed to a 2940UW..tried w/o luck 😀
Check your card and let me know which it is similar too.
added # 2: It did not hurt my non upgraded card when I tried to flash it, still works fine but no true 8Gb+ support.....

Thought I should add that if the card cannot be upgraded IF it has a flashable EEPROM like both of mine is because Adaptec used the EEPROMS built in "JEDEC Standard Software Data Protection (SDP) 3-byte command sequence." which if not presented proper in the flash program then the it will not update. Not a guru but figured that the OEM cards were written with a different 3 byte than the retail so the retail flash upgrade would not work. Have tried to find the Dell 2940U bios upgrade a few times but never found one. Dell was the main purchaser (by numbers) of Adaptec oem cards, Micron also bought a bunch so if we could find the upgrades by them (if they exist) it could help both of us and many others too.
Anyway just tossing out some thoughts...If that EEPROM was not soldered would be easier to force flash with a TL886. just my thoughts and opinion....
