Sorry for the late replay.
Currently I have the PC P3 at the computer technician shop in order to test the Syba PCI SATA card: SD-SATA150R with SIL3512 chipset.
I checked the PCI card BIOS and is it the version 4.3.83. I then used correctly the PCI card, after several failed attempts with the wrong drivers, finally founding the right driver on the official Silicon Image website:
- Silicon Image Serial ATA Raid driver for the SiI 3x12 controllers Ver 188.8.131.52 (File found on website: 3112Raid_x86_10600_logo.zip).
The SATA HD drive is recognized correctly but the data transfer speed seems quite similar to that of the other HD drive Pata!
At first impression it seems to me that the limit, right in my case of the old PC P3, is given instead by the motherboard (11 years old!)
These are the PC specs:
Intel Pentium IIIE Coppermine 700MHz, Socket 370, RAM 512Mb, MotherBoard PCChips M754LMR+, Chipset ULi/ALi M1631 ALADDiN TNT2, VideoCard NVIDIA Aladdin TNT2.
Over the next few days I will give more precise information about the speed that I found in the following 3 cases:
PATA HD (attached to the motherboard), HD Sata (attached to PCI card), USB 2.0 HD (attached to USB 2.0 PCI card).
Thank you from Italy for your help, for your kindness and availability!
Note 1: So far I have not received any useful indication from the Syba support, despite the message I sent them through its official website, but at this point it becomes really irrelevant.
Quote: 'DMA checkbox comes with the default Windows drivers. Specific drivers may have one or not, at a different location. They often have no such checkbox because they always enable DMA and UDMA.'
A.: I my case, in the driver's installed properties there isn't any indication of DMA checkbox, but the transfer speed is not anymore the previous slow 1 Mb/sec resulting without any driver installed!
PS: In order not to use any internal HD drive, as would be nice and sweet to run the Win98SE operating system on an external USB 2.0 HD drive, booting from a floppy disk if necessary!
