Hey everyone,

I’m trying to recover a dead BIOS chip after flashing the wrong image using awdflash.exe.

The chip markings are:
H.T M11614T C9706

ChatGPT suggested this is likely a Macronix MX29F010 / MX29F010B clone, 128 KB × 8, 5 V parallel flash in a DIP-32 package.

I bought a programmer and using XGPro v13.04 software (T48 / TL866-3G)

IC type tried in XGPro:
AT29C010A
W29C010
AM29F010B
MX29F001B (closest Macronix option)

What I’ve Done So Far

Erase reports success (≈15 s) for AM29F010B, W29C010, etc. with Check ID off

Blank check always fails → “Not empty! FLASH ADDR 0x000000 CHIP DATA 0x25”.

Read afterwards still shows data → erase clearly didn’t happen.

Self-diagnostic on the T48 passes (VPP ≈ 12 V OK).

Tried “Erase → Erase again” and “Unprotect before programming” options → no change.

So it looks like the T48 isn’t sending the correct erase sequence for this specific chip (perhaps due to a top-boot or clone command-set mismatch).

What I’m Hoping to Confirm

Is AM29F010B indeed the right device to select in XGPro for this chip?

Has anyone successfully erased or programmed a similar H.T M11614T / MX29F010B chip with the T48?

If not, what’s the easiest drop-in replacement (DIP-32 1 Mbit 5 V Flash) that works reliably with the T48?

would any of these work ?

Any advice, working device-type settings, or confirmation of a compatible replacement would be hugely appreciated.
Thanks!

Almost all DIP-32 Flash ROMs have the same pin layout, so if you have a spare T48-compatible Flash ROM on hand, it's a good idea to switch to that.

Anyway:
- On the XGpro, I'm sure the Flash ROM's ID was displayed when Check ID failed. This might give you a clue.

LLM rarely gives the right answer on these topics.
Trying the wrong flashing method can permanently damage your ROM (I destroyed an Intel 29F001 a while back), so be careful.

Thanks for the reply.

I am completely new to Xgpro and the programmer. Where can I see the ID?

when I click on ID check I get

C2 1A

how does that help me work out the IC type?

Chip IDs are two bytes: the manufacturer ID and the product ID.
C2 = Macronix
1A = MX28F1000P
