Help dumping BIOS using SwapMagic and USB

I followed a number of different guides but to no avail. The SwapMagic disc works when booted without the USB drive in but whenever I plug it in and boot it the screen just goes black after the "PlayStation 2" logo and nothing happens. I formatted the USB flash stick to FAT32 and created a folder named SWAPMAGIC. I'm using the file from this website: http;//pcsx2,net/download/releases/tools/viewcategory/14-tools,html , specifically the binary one. I took the ps2dumper,elf file and renamed it SWAPMAGIC,elf then stuck it in the SWAPMAGIC folder. What exactly am I doing wrong? Please help. >.< (Also I'm not being allowed to post "links" so just replace the commas with periods and semicolons with colons as necessary...)

Your best bet way is get a copy of uLaunchELF rename it to SWAPMAGIC.ELF in FOLDER of same name use it to launch the ps2dumper.elf

but you may have an incompatible USB stick for swapmagic too

Finally got it using this guide: http;//www,ngemu,com/forums/showthread,php?t=88854 Definitely recommend! Thanks for thee response!
