What is the largest Flash card I can use in the Poqet PC Plus?
According to Tristan Henderson (tristan [at] pointystick [dot] com): I have been doing some more work on the PQCARD.EXE ATA driver on the Poqet to see if the FLASH card size limit can be improved. During this work I have found that the current size limit is actually 32MB. This has been determined by looking at the device driver header created by the program. The attribute word shows that the driver does not support 32-bit sector addressing. This means the maximum number of sectors supported is 65535 (16 bits). When multiplied by 512 Bytes/Sector we arrive at 32MB. The worst part is that no warning will be given if larger cards are used they will appear to work at first. An examination of how addressing is handled from the driver request through to the ATA interface also confirms that the addressing is 16 bit only. I’m aware of reports of using larger cards with success. I can only assume this is because the card has only been partially filled. If you try filling card that is larger tha
