I've been trying to downgrade to Windows XP on my SL400, currently with Windows 7 Pro installed. Since my DVD drive has been defective for some time, I made a bootable USB with Windows XP loaded on it via Win2Flash. Having booted the machine on USB and initiated the XP setup sequence, the computer suddenly hits a BSOD as the setup is initializing (before I actually do anything in the setup)... with the following message:
0x0000007B (0xF78D2524, 0xc0000034, 0x00000000, 0x0000000)
Not sure if that gives any indication of what it is, but its the only non-generic BSOD message that shows up.
Is there any way to get XP on this machine or is it a lost cause?
Thanks in advance!

I have personally tried to install Windows on X40 using a jump drive via Win2Flash and came across same BSOD, the probable [not certain] cause is that XP needs to be provided with drivers for USB drive. I have come to the conclusion that installing XP via USB drive is a very tricky business, and now I'm not even sure if it's possible on thinkpads, although it has worked for me on desktops though.
Nevertheless, I have one suggestion for you, before booting through the USB drive try going into BIOS and set SATA AHCI mode to Compatibility for the HDD. It may work. If not then you can buy an external USB optical drive, it'll be much cheaper than internal drive for your SL400.
Hope it helps.
