It's not actually burned into a ROM, but NVFLASH memory onboard where the compressed firmware code gets stored. After you do a factory reset, it wipes the system and data caches from regular memory. When you reboot, it takes much longer as the system files are expanded, copied to the cache location and then optimized in the Dalvik cache, and that's where the system runs. And that's also why a reset clears away issues, as the old cache data is wiped and replaced with freshly optimized cache that works better with the OS Kernel.

This applies to all versions of the Galaxy Tab 10.1, including the WiFi models, 3G models from Rogers, Bell and Telus, and international versions used in the EU.

Speaking of European models, for fun I flashed the UK version on my Rogers Tab and now have a cleaner install of ICS, free of the Rogers crapware and settings. It's cleaner, works well and I'm very happy with the ICS update. I also unlocked my Tab and can use any compatible carrier's SIM card...sweet.
