1. Mass Storage Cabinets

Enabling AHCI in a system BIOS will cause a 0x7B Blue Screen of Death STOP error (INACCESSIBLEBOOTDEVICE) on installations of Windows XP where AHCI/RAID drivers for that system's chipset are not installed. I am having the same problem. Replacing the modified ntdetect.com does not solve the problem for me.I got it to work after I change the sata mode in bios from AHCI to compatibility. Any idea whyHonestly it puzzles me a lot.

This error basically means, that your boot device is no longer accessible. Since during Text mode the boot device is your USB disk/stick, what drivers you have for your disk controller should NOT matter, it simply wouldn't find your hard disk.The modified ntdetect.com resolves problems with some buggy BIOSes, when USB bus is reset and USB peripherals re-enumerated.

Many Dells have this problem. And it makes sense to get BSOD 7B in that case.But why your (missing?) disk controller driver causes same I can only guess- first would be driver conflicts.What is your disk controller/motherboard?Do you have any third-party mass storage drivers integrated in your source?Are you using original MS windows disk as source, even if you Nlited it?As Wimb mentioned, most of this problems are resolved by using BTS mass storage drivers pack, for me it's a must. @ilkotSorry I tried to 'beautify' your post using codebox - / codebox tags instead of code - / code ones, but the board fails the parsing, please do recheck the data, I may have unwantingly introduced some changes while testing the output.@allPlease find here the references, within the LOONG XP on USB thread, about modifying NTDETECT.COM:(post #3)before you ask for a direct download or something like that, do read this:'level #4' people should NOT 'play' with this kind of things, they may well find thenselves with an unbootable systemjaclaz Edited February 17, 2008 by jaclaz. You may try the modified ntdetect.com as mentioned. Spectrasonics atmosphere rar. Copy and paste all in Tiny Hexer (freeware), select HEX TEXT, save as ntdetect.com and put it in USB stick root, filesize must become 47,596 bytes.

I don't know other ways to give you this file without breaking forum and MS rules. (.)I was also having the BSoD during the TXT Mode (using Windows XP Professional with slipstreamed SP2, Polish version), but after applying the modified ntdetect.com file the BSoD is no more. Everything seems to work perfectly.
