Ah, glad you mentioned that, (as I too have made large bootable FS's on USB, but only tested on amd64 so far & had forgotten i386 limits) Some non PCs also dont want more than 2G SDRAM, eg SDRAM player car radio transmitter http://www.berklix.com/~jhs/txt/renkforce-fm-16.html it plays from 2G SDRAM with an MBR & FAT, but the manual says <= 2G. I suppose 32 bit CPUs will freak at/above 4G = 4,294,967,296 & what with cavalier mixing on int / unsigned, above 2G may be tempring fate. http://www.cnet.com/laptops/sony-vaio-vgn-sz340/4505-3121_7-32328541.html Intel Core 2 Duo T7200 / 2.0 GHz http://www.intel.com/content/www/us/en/search.html?keyword=T7200 http://ark.intel.com/products/27255/Intel-Core2-Duo-Processor-T7200-4M-Cache-2_00-GHz-667-MHz-FSB?wapkw=t7200 Instruction Set 64-bit Hmm, so that's not the reason Lev is hanging then.
