This seem a good thread for this post. I am working on a Dell (yuk) Dimension 2400. Here is some info. BIOS, as best I can tell from the chip and Setup. SST 49LF004B (from chip) Ver. A05 (from setup. MOBO Intel D865gbf, or Foxconn LS-36, can't get part number from Dell (imagine that) Chipset 845GV CPU Celeron 2.4 Ghz Basically, all I did was put the HDD and CD/DVD recorders from a Dimension 4600 in place of the existing hardware. It took a few tries with the BIOS to get it to boot, but it booted and was working well. Then my sis decided she wanted XP PRO instead of the XP Media Center. So I wiped the HDD with killdisk. And from there it all went South. When I try to install XP PRO I get "Diskette drive 0 seek failure" I assumed it was looking for a non-existant floppy, so I went into BIOS and made sure that the floppy option was disabledand that CD/DVD was my first boot choice. All my drives show up in setup. No beeps on starup, and all diagnostic lights are green. If I let it sit awhile I get Code: =======TRAP 0000000D - General Protection Fault======= Among the several other things it says on the same screen are Code: errcode=2BD0 NoCy NoZr IntDis Down TrapDis. This seems as if it should be easy, but I cant figure it out. Any help will be greatly appreciated.
Well...DUH. Looked in BIOS again and checked Drive Config. Found Floppy, and changed it to "not installed"
