INT 6F corresponds to IRQ23 on the original HP Vectra AT, which is unavailable because of its use as a BIOS extension software interrupt the INT 6F handler consists of an instruction to load DS with the driver's data segment followed by an indexed far jump using BP to select the destination vector; since the interrupt handler is located immediately following the dispatch table, the HP_VECTOR_TABLE may be found by looking at offset 0000h in the INT 6F segment, and its size is equal to the offset of the interrupt handler each entry in the HP_VECTOR table consists of a DWORD for the driver's entry point address and a WORD for the driver's data segment this function is not user-callable, as it is a response to a physical event, and assumes that the caller has already handled the physical interrupt and updated the Describe Record (see #03749) to reflect the event SeeAlso: INT 6C"HP Vectra",INT 6F/AX=0200h"HP Vectra" (Table 03741) Values for HP Vectra EX-BIOS driver ID:

It utilizes some undocumented 386+ features to enable 4G code and data segments (flat memory model) in the CPUs real-mode. It is not compatible with V86-mode (as with most EMM386). For maximum speed and compatibility with DOS it uses a two stage interrupt model (see #03791) SeeAlso: #03789,#03790,#03791 (Table 03789) Call HugeRealMode Server "Disable A20" function with: AL = 01h Return: AX = error code (see #03787) SeeAlso: #03788,#03790 (Table 03790) Call HugeRealMode Server "Query A20 State" function with: AL = 02h Return: AX = A20 state (0000h disabled, 0001h enabled) SeeAlso: #03788,#03789 (Table 03791) Call HugeRealMode Server "Enable Two-Stage Interrupt Model" function with: AL = 03h Return: AX = error code (see #03787) Notes: If the two stage interrupt model is disabled, the IP must stay below 1MB, because the high word of EIP is not saved correctly by the standard interrupt management in real mode. Routines in extended memory may only be called with interrupts disabled (only usable for very short routines). If the two stage interupt model is enabled, these conventions are not required. The outer (transparent) ISRs save the higher word of EIP in the high word of CR3 (possible modification: in memory, if this is not safe) and then invoke the standard ISRs. Because of this handling, one should use pseudo segmented code even in extended memory (64K blocks located on 64K boundaries) to avoid the misalignment of the saved EIP (in CR3). Another way is to track and realign CR3 each time when jumping over a 64K boundary in extended memory SeeAlso: #03788,#03792 (Table 03792) Call HugeRealMode Server "Disable Two-Stage Interrupt Model" function with: AL = 04h Return: AX = error code (see #03787) SeeAlso: #03788,#03791 (Table 03793) Call HugeRealMode Server "Get Segment Address Of Server-Management Range" with: AL = 05h Return: AX = error code (see #03787) ES = segment address SeeAlso: #03803 (Table 03794) Call HugeRealMode Server "Allocate Memory" function with: AL = 06h DX = length in KB Return: AX = error code (see #03787) DX = handle EBX = start address of allocated block SeeAlso: #03795,#03796 (Table 03795) Call HugeRealMode Server "Deallocate Memory" function with: AL = 07h DX = handle Return: AX = error code (see #03787) SeeAlso: #03794,#03796 (Table 03796) Call HugeRealMode Server "Modify Allocated Memory Size" function with: AL = 08h DX = handle BX = new size in KB Return: AX = error code (see #03787) EBX = new address SeeAlso: #03794,#03795 (Table 03797) Call HugeRealMode Server "Load .XMF-file" function with: AL = 09h ES:BX -> filename (see #03798) Return: AX = error code (see #03787) ECX = target address Notes: memory must be allocated before loading .XMF file format (eXtended Memory executable File format) is supported by the HugeRealMode server for easier handling of XMS-code.
