  A quick IDE to SATA Adapter test:
 

 
  Nice to see both SATA HDD and 11MB chip+500MB fast!
 
  So now we can use SATA HDDs/SSDs/DVD-RWs with interface converter,
  with speed penalty from SATA/SATA2/SATA3 to our EIDE. What is EIDE Speed on v4? UDMA 133 or UDMA 176 or lower?

  Once Standalone is out some converter might be available, but for now its best to get V4 Vamp for A500. Might be cheaper and convenient, provided that A500 board is healthy and recapped.

  Why does the chip ram start at $4000? Shouldn't it start at $0?
 

  Does it really matter if they provide 4-11MB FAST mappable and usable as fastest chip RAM ever?

The documentation from Commodore does say that chip RAM starts at $0 (not withstanding the points already made about what the 68k cpu does with these starting addresses).

EXTERNAL LINK 
But googling "amiga showconfig" reveals a variety of chip ram starting points.........none of which are $0.

This merely a question of curiosity more than a concern.  But the question is interesting to me.  Did Kickstart need to be patched for this.  The memory range collides with Auto-config address ranges. On a Zorro-Slotless V4 standalone this is point is likely mute.  But on a A500/A2000 this might come into play.

It would be good if someone with deeper insights into the Amiga internals could delve into this a little.  As someone who is re-exploring AOS3 development, I am wondering if I need to account for this in anyway or if i can simply AllocMem( 10Mb, MEMF_CHIP ) and reasonably expect it to work.  Not that one needs such an allocation typically.  ;-)

The wonders of the Apollo Core continue. :-)

The first KBs at $0 area are used by Shapeshifter for MAC Emulation.

Yes, this will work.

The DMA of AMIGA chipset in the V4 can access _ALL_ 512 MB of memory. This means Audio, Copper, Sprites can be played/shown from all 512 MB.

You have to mind that in reality the reached speed
is limited by AMIGA OS - not by the IDE Interface.

This means if the INTERFACE peak speed runs 100 or 200 or 500 does not matter to the user in the end.

What matters is the MB/sec that you can reach in real world - including all the overhead of the Driver and OS.

Thanks, I thought it could be something like that, but I didn't know for sure.

What is the MB/sec on the V4 IDE interface? Does it do DMA?

  Too bad this was not touched in OS 3.1.4 update I suppose.
  Does IDE Fix 97 or other drivers help improve the matter?
 
  What is speed relevant to old days SCSI and Amiga IDE speeds?
  How does USB fare? So if the card remains fastest exchange device, could it be extended and IDE device used for boot?

Could AROS and MINT / Linux m68k fare better then AmigaOS with proper drivers? :-)

MicroSD slot is now enabled and also RTG works with the AGA.

Nice progress indeed!

  Just to make it aclear, SD slot boot for v2 and v4
  and RTG and AGA for V4s or also for v2?

Vampire can't boot from SD slot and it needs a driver to read SD cards.

This thread is about Standalone V4 bring-up. Here's nothing V2 related updates.

OK, so this is V4 only progress. Agreed.
V4 will be able to boot from SD?

Theoretically yes, but it is not a high priority. First we need to get SAGA fully ready.

If that gives fast Blit, SAGA true col., rudeimentary 3D and 16-bit audio, understandable as it is "the next revolution" after the fast CPU and acceptable levels of compatibility out of box.

Personally, I am more interested in SADA2IDE SSD boot, but then again if its offers not that much speed due to OS limitations - fast,reliable and cheap media such as SD can be a savior.
