+`usbutils` provides `lsusb` (used to verify the CH341A). `chafa` and the
+`libwebp` tools are optional — the interactive script uses them to render
+reference images inline in your terminal when supported (and to transcode
+webp images to png if your chafa build doesn't support webp natively).
+Without them the script falls back to printing a URL.

 ## Disassembling the Laptop
 1. **Power off your laptop**: Make sure your T440p is completely powered off and unplugged from any power source.
 2. **Remove the battery**: Flip the laptop over and remove the battery by sliding the latch to the unlock position and lifting it out.

 ## Locating the EEPROM Chips

 ## Assembling the SPI Flasher

 ## Extracting Original BIOS

-Next, extract the original rom from both EEPROM chips. This is 
-done by attaching the programmer to the correct chip and running
-the subsequent commands. It may take longer than expected, and 
-ensuring the bios was properly extracted is important before proceeding
-further.
+Next, extract the original ROM from both EEPROM chips. Do the **4MB (top)
+chip first** — it's the smaller of the two, so reads finish faster and any
+setup issues (clip alignment, pin 1, voltage) surface quickly. Then move
+the clip to the **8MB (bottom) chip**.
+
+Each chip is read twice so the two reads can be diffed to catch flaky
+contact. The reads can take a while (tens of seconds to a couple of
+minutes per pass) — that's normal.
