Lecroy x-stream wavepro 7300, DDA-5005, SDA-6000A oscilloscopes upgrade

I would like to describe simple but efficient upgrade for Lecroy wavepro 7k (7100, 7200, 7300, 7300A, 7200A, DDA-3000), partially DDA-5005, SDA-6000A and maybe other Lecroy oscilloscopes.
Lecroy software are single threaded and very poorly optimized, for example 10Mpts FFT take only 60-65% of one core(second core don't used at all) in dual core 3.86Ghz i5-680. Thats why no need to use very fast multicore processors, they will still not be used at their full power.

For upgrade first of all you need to replace old MB, processor, cooler, memory, HDD with such:

1. ASUS P5PE-VM motherboard, with 865G chipset supporting Lecroy DVO card, Core 2 Duo processors and SATA ports.
2. Core 2 Duo 2.6Ghz E4700 or with patched BIOS Pentium Dual Core 3.2Ghz E5800.
3. DDR 400 CL2 Memory such as OCZ Platinum OCZ4002048ELDCPE-K
4. SATA SSD such as Intel X25-M G2
5. Intel low profile Al-Cu cooler

This will boost computation speed 10x compared to Lecroy`s 7300 default processor, and dramatically reduce startup time.

Also i create WinXP installation disc with latest XP Embedded updates, optimizations for 10" display, uniprocessor HAL by default(no need for new front panel driver), etc. You can download it here.

Patched BIOS (by LLC) can be downloaded here.

Secondly seal case in the fan area, and replace Panaflo FBA12G12U with Nidec servo D1225C12B6, this will reduce noise 5-6 times! with ADC&MFE temperature lowered by 0..2 degree. Only this unique "Gentle Typhoons" can be used, with another low speed fans temperature rise would be unacceptable +10 deg, even with good Sanyo denki 9G1212M1011 temp rise would be up to +3 deg. Also replace Panaflo FBA09A12H with Sanyo denki 9G0912H or Nidec servo D0925C12B4.
