    5 XTIDE Universal BIOS is mainly used with XTIDE controller[1] that makes possible to use modern IDE drives on PC/XT systems. XTIDE Universal BIOS does more than that since it support 16- and 32-bit transfers too. 16-bit transfers are meant for 16-bit ISA controllers and 32-bit transfers are meant for VLB and PCI controllers.

    35 The most convenient way to use XTIDE Universal BIOS is to use XTIDE card[1]. It can be used on any PC with free 8-bit ISA slot. You might not want to connect any drives to it in 16- or 32-bit systems since 8-bit transfer will be very very slow. Using XTIDE card allows EEPROM flashing so it is really easy to update XTIDE Universal BIOS.

    3736Another option is to use any card with free ROM socket for 8 kiB or larger ROMs. Official XTIDE builds are meant for 8 kiB ROMs but you can burn it on larger ROM if you append enough zeroes to the end (only append zeroes so checksum does not change). Many network cards have unused ROM sockets but there are also few multi I/O cards and IDE controllers with ROM sockets.

    358 16-bit ISA IDE controllers are very simple ISA<->PATA adapters and they all perform alike. ISA is not fast enough for anything above PIO-0 transfer method (theoretical maximum 3.3 MB/s)[2].
     35716-bit ISA IDE controllers are very simple ISA to PATA adapters and they all perform alike. ISA is not fast enough for anything above PIO-0 transfer method (theoretical maximum 3.3 MB/s).
    359358
    360359VLB and PCI IDE controllers are much more complex since they have an actual controller between bus and IDE drive. This controller can buffer words so CPU can read 32-bits at a time. Later VLB and (all?) PCI controller also offer flow control so they can support PIO modes 3 and 4. Early VLB controller are limited to PIO-2. Later VLB multi I/O cards have two IDE connectors so you should use one of those even if you don't need the other IDE connector.

    375 CF cards and microdrives are IDE devices and should work as any hard disk. Unfortunately there are many CF cards and microdrives with limitations. Some of them only work as a master drive and not as a slave drive. Many of them are not bootable even though they otherwise seem to work fine. Avoid CF cards without speed ratings. They are too slow to be used as a hard disk replacements.

Some of them only work as a master drive and not as a slave drive. Some of them requires MBR to be re-created before they can be booted. Avoid CF cards without speed ratings. They are too slow to be used as a hard disk replacements.

     376MBR can be re-created with FDISK /MBR switch. You can also use any low-level data wipe utility to clear non-bootable MBR. MBR will then be created automatically when partitioning the drive.
